mail/dovecot2: Update to 2.3.21

Changelog:
* lib-oauth2: Allow JWT tokens to be validated with missing typ field.
  The typ field is left out by some key issuers to conserve space,
  notably kubernetes. Now missing typ is tolerated, but if present, it
  still must be "jwt".
+ auth: Auth passdb and userdb reply can contain "event_<name>=value"
  which will be added to login event and mail user event respectively.
+ lib-master: Set process title during various initialization stages to
  clearly describe what the process is waiting on.
+ lib-storage: The mail_temp_scan_interval is now fuzzed incrementing it
  by 0..30% based on username's hash to reduce the chance of load spikes.
+ lib-storage: The temp file scan has been moved from the open of the
  mailbox to the close, to reduce the latency perceived by users.
+ stats: If metric has fields specified, all these fields are
  exported as counters to prometheus exposition.
  See https://doc.dovecot.org/configuration_manual/stats/openmetrics/.
- *-login: Processes might have crashed when a SSL connection disconnects
  uncleanly.
- acl: When plugin was loaded \HasChildren and \HasNoChildren flags
  were calculated incorrectly for mailboxes containing '*' and '%'
  in their names.
- auth: Crash occured if a connection to PostgreSQL database server
  failed during startup.
- auth: Logins with invalid passwords (e.g. unknown scheme) in passdb
  were failing with "password mismatch" instead of "internal error".
- auth: XOAUTH2 and OAUTHBEARER mechanisms were not giving out protocol
  specific error message on all errors. This especially broke OIDC
  discovery.
- dbox: When last_temp_file_scan header wasn't set (especially after
  dsync migration), the next mailbox open always triggers the temp file
  scan. This could have caused a load spike after migrations. Fixed by
  using the mailbox directory's atime when the header isn't set, which
  usually moves the scan time into the future.
- dict-redis: A crash would occur on transaction rollback.
- dsync: Infinite loop causing out of memory would occur when handling
  mailbox deletion from remote end and hierarchy separators would differ.
- dsync: Incremental dsync failed for folder names ending with '%',
  unless BROKENCHAR was set. Also folder names with '%' elsewhere in
  them caused each incremental dsync to unnecessarily rename the folder
  to a temporary name and back. v2.3.19 regression.
- imap-hibernate: If an IMAP client unhibernation timed out with
  "(version received)", the unhibernation could still have successfully
  finished later on and continued working normally. This was rather
  confusing, because imap-hibernate already logged that the client got
  disconnected. Avoid this by forcing the connection to shutdown on
  unhibernation timeout.
- imapc: Crashed when a folder mapped through the virtual plugin
  disappears from the storage.
- imapc: EXPUNGE, EXISTS or FETCH replies from a server for a previously
  selected mailbox could have been processed as if they belonged to the
  new mailbox currently being selected. This could have caused warnings.
- lib-http: Dovecot HTTP server (doveadm, stats/openmetrics) may have
  disconnected HTTP clients before the response is fully sent. This
  happened only on busy servers where kernel's socket buffers were
  rather full.
- lib-http: Fixed a potential crash on http-server if a client
  disconnected early. v2.3.18 regression.
- lib-index: Index file corruption could have caused a crash. Fixes:
  Panic: file mail-transaction-log-view.c: line 165 (mail_transaction_log_view_set):
  assertion failed: (min_file_seq <= max_file_seq).
- lib-index: Purging an existing >1GB cache file can crash. Now cache
  files still above 1GB after purging are removed. Fixes:
  Panic: file mail-index-util.c: line 10 (mail_index_uint32_to_offset):
  assertion failed: (offset < 0x40000000)
- lib-lua: A HTTP client could not resolve DNS names in mail processes,
  because it expected "the dns-client" socket to exist in the current
  directory.
- lib-oauth2: Dovecot would send client_id and client_secret as POST
  parameters to the introspection server. These need to be optionally in
  Basic auth instead.
- lib-oauth2: JWT aud validation was not performed if aud was missing
  from a token, but was configured on Dovecot.
- lib-oauth2: JWT key type check was too strict.
- lib-oauth2: JWT token audience was not validated against client_id as
  required by the specification.
- lib-ssl-iostream: Using the ssl_require_crl=yes setting may have caused
  CRL check failures for outgoing SSL/TLS connections, although it was
  supposed to affect checking CRLs only for client-side SSL
  certificates. v2.3.17 regression.
- lib-sql: MySQL driver leaked memory when connection failed.
- lib-storage: Various fixes when running into out of disk space.
- master: Service idle_kill setting didn't work properly on busy
  servers. It was very unlikely that any process was idling long enough
  to become killed. Also the idle_kill handling code was using quite a
  lot of CPU on the master process when there were a lot of processes
  (e.g. imap). The new behavior is to track the lowest number of idling
  processes every idle_kill time interval and then kill that many idling
  processes.
- mdbox: Temp file scan was done for always empty directories.
- mdbox: The fdatasync() call was done in wrong parent directory when
  writing mails. Also on a failure it crashed instead of logging an error.
- notify_status: The plugin crashes if any user initialization fails.
- pop3: Sending command with the ':' character caused an assert-crash.
  v2.3.18 regression. Fixes: Panic: event_reason_code_prefix(): name has ':'
- stats: Fix panic when a nonexistent event exporter was referenced while
  adding a new metric dynamically via doveadm stats add. This produces
  a proper error now.
- stats: If process exported a lot of events and then exited, some of
  the last events may have become lost.
- stats: Invalid Prometheus label names were created with specific
  histogram group_by configurations. Prometheus rejected these labels.
- welcome: The plugin didn't execute in some situations that created
  INBOX but didn't open it, e.g. if GETMETADATA was used before the
  INBOX was opened.

dovecot2: updated to 2.3.19

v2.3.19

+ Added mail_user_session_finished event, which is emitted when the mail
  user session is finished (e.g. imap, pop3, lmtp). It also includes
  fields with some process statistics information.
  See https://doc.dovecot.org/admin_manual/list_of_events/ for more
  information.
+ Added process_shutdown_filter setting. When an event matches the filter,
  the process will be shutdown after the current connection(s) have
  finished. This is intended to reduce memory usage of long-running imap
  processes that keep a lot of memory allocated instead of freeing it to
  the OS.
+ auth: Add cache hit indicator to auth passdb/userdb finished events.
  See https://doc.dovecot.org/admin_manual/list_of_events/ for more
  information.
+ doveadm deduplicate: Performance is improved significantly.
+ imapc: COPY commands were sent one mail at a time to the remote IMAP
  server. Now the copying is buffered, so multiple mails can be copied
  with a single COPY command.
+ lib-lua: Add a Lua interface to Dovecot's HTTP client library. See
  https://doc.dovecot.org/admin_manual/lua/ for more information.
- auth: Cache lookup would use incorrect cache key after username change.
- auth: Improve handling unexpected LDAP connection errors/hangs.
  Try to fix up these cases by reconnecting to the LDAP server and
  aborting LDAP requests earlier.
- auth: Process crashed if userdb iteration was attempted while auth-workers
  were already full handling auth requests.
- auth: db-oauth2: Using %{oauth2:name} variables caused unnecessary
  introspection requests.
- dict: Timeouts may have been leaked at deinit.
- director: Ring may have become unstable if a backend's tag was changed.
  It could also have caused director process to crash.
- doveadm kick: Numeric parameter was treated as IP address.
- doveadm: Proxying can panic when flushing print output. Fixes
  Panic: file ioloop.c: line 865 (io_loop_destroy): assertion failed:
  (ioloop == current_ioloop).
- doveadm sync: BROKENCHAR was wrongly changed to '_' character when
  migrating mailboxes. This was set by default to %, so any mailbox
  names containing % characters were modified to "_25".
- imapc: Copying or moving mails with doveadm to an imapc mailbox could
  have produced "Error: Syncing mailbox '[...]' failed" Errors. The
  operation itself succeeded but attempting to sync the destination
  mailbox failed.
- imapc: Prevent index log synchronization errors when two or more imapc
  sessions are adding messages to the same mailbox index files, i.e.
  INDEX=MEMORY is not used.
- indexer: Process was slowly leaking memory for each indexing request.
- lib-fts: fts header filters caused binary content to be sent to the
  indexer with non-default configuration.
- doveadm-server: Process could hang in some situations when printing
  output to TCP client, e.g. when printing doveadm sync state.
- lib-index: dovecot.index.log files were often read and parsed entirely,
  rather than only the parts that were actually necessary. This mainly
  increased CPU usage.
- lmtp-proxy: Session ID forwarding would cause same session IDs being
  used when delivering same mail to multiple backends.
- log: Log prefix update may have been lost if log process was busy.
  This could have caused log prefixes to be empty or in some cases
  reused between sessions, i.e. log lines could have been logged for the
  wrong user/session.
- mail_crypt: Plugin crashes if it's loaded only for some users. Fixes
  Panic: Module context mail_crypt_user_module missing.
- mail_crypt: When LMTP was delivering mails to both recipients with mail
  encryption enabled and not enabled, the non-encrypted recipients may
  have gotten mails encrypted anyway. This happened when the first
  recipient was encrypted (mail_crypt_save_version=2) and the 2nd
  recipient was not encrypted (mail_crypt_save_version=0).
- pop3: Session would crash if empty line was sent.
- stats: HTTP server leaked memory.
- submission-login: Long credentials, such as OAUTH2 tokens, were refused
  during SASL interactive due to submission server applying line length
  limits.
- submission-login: When proxying to remote host, authentication was not
  using interactive SASL when logging in using long credentials such as
  OAUTH2 tokens. This caused authentication to fail due to line length
  constraints in SMTP protocol.
- submission: Terminating the client connection with QUIT command after
  mail transaction is started with MAIL command and before it is
  finished with DATA/BDAT can cause a segfault crash.
- virtual: doveadm search queries with mailbox-guid as the only parameter
  crashes: Panic: file virtual-search.c: line 77 (virtual_search_get_records):
  assertion failed: (result != 0)

dovecot2: PLIST fix for options

dovecot2: updated to 2.3.17

2.3.17

* Dovecot now logs a warning if time seems to jump forward at least
  100 milliseconds.
* dict: Lines logged by the dict process now contain the dict name as
  the prefix.
* lib-index: mail_cache_fields, mail_always_cache_fields and
  mail_never_cache_fields now verifies that the listed header names are
  valid. Especially the UTF8 "–" character has sometimes been wrongly
  used instead of the ASCII "-".
+ *-login: Added login_proxy_rawlog_dir setting to capture
  rawlogs between proxy and backend.
+ dict: The server process now keeps the last 10 idle dict backends
  cached for maximum of 30 seconds. Practically this acts as a
  connection pool for dict-redis and dict-ldap. Note that this doesn't
  affect dict-sql, because it already had its own internal cache.
+ doveadm: New stats add/remove commands added to support changing the
  metrics configuration on runtime.
+ lazy_expunge: Added lazy_expunge_exclude settings to disable
  lazy_expunge for specific folders. \Special-use flags can be used as
  folder names.
+ lib-lua: Added a new helper function dovecot.restrict_global_variables()
  to disable or enable defining new global variables.
- LAYOUT=index List index rebuild was missing.
- LAYOUT=index: Duplicate GUIDs were not detected.
- acl: When using acl_ignore_namespace Dovecot attempted to access or
  create dovecot-acl-list even when the namespace should have been
  ignored. For virtual namespaces this could have yielded errors about
  "Read-only file system" or "Permission denied".
- auth: Setting the "master" passdb field to empty value would
  cause proxying to fail with an authentication error.
  Now an empty "master" field is ignored.
- doveadm-server: Duplicate error lines were sent for failed commands.
  This didn't normally cause visible problems, except when using
  wildcards in usernames or -A parameter to go through multiple users.
- doveadm-server: Logs written by doveadm-server were often missing log
  prefixes, especially mail_log_prefix for mail commands. Logs sent to
  doveadm TCP client were also missing log prefixes.
- doveadm: v2.3 regression: batch command always crashes.
- doveadm: v2.3.11 regression: Commands failed if ssl_cert or
  ssl_key files weren't readable by the user running doveadm, even
  though doveadm didn't actually use these settings
- imap-hibernate: Process may crash at deinit:
  Panic: file ioloop.c: line 928 (io_loop_destroy): assertion failed:
  (ioloop->cur_ctx == NULL).
- imap: Using imap_fetch_failure=no-after can cause assert-crash
  with some IMAP commands if reading the mail fails (e.g. wrong cached
  mail size). Fixes:
  Panic: file index-mail-headers.c: line 198 (index_mail_parse_header_init):
  assertion failed: (!mail->data.header_parser_initialized)
- imap: v2.3.10 regression: When using INDEXPVT to enable private
  \Seen flags (for shared or public namespaces) the STORE command did
  not send untagged replies for the \Seen flag changes.
- imap: v2.3.15 regression: If PREVIEW/SNIPPET is not the final FETCH
  option in the command, the IMAP FETCH response is broken.
- imap: v2.3.15 regression: MOVE command leaks mailbox if it can't be
  opened and crashes at deinit:
  Panic: file mail-user.c: line 229 (mail_user_deinit): assertion failed:
  ((*user)->refcount == 1).
- imapc: Copying nonexistent mail via imapc could have crashed. Fixes:
  Panic: file mail-storage.c: line 2385 (mailbox_transaction_commit_get_changes):
  assertion failed: (ret < 0 || seq_range_count(&changes_r->saved_uids) == save_count ||
  array_count(&changes_r->saved_uids) == 0).
- indexer: v2.3.15 regression: Process crashes if indexer-client
  disconnects while it's waiting for command reply. This happened for
  example if IMAP SEARCH triggered long fts indexing and the IMAP
  client disconnected while waiting for the reply.
- indexer: v2.3.15 regression: Process may have crashed in some situations.
- indexer: v2.3.15 regression: indexer-worker processes may not have
  reached the process_limit in some situations, possibly even using just
  one indexer-worker process even though there were many indexing
  requests queued.
- lib-compression: Reading lz4 compressed mdbox mails may crash. Fixes:
  Panic: file istream.c: line 345 (i_stream_read_memarea):
  assertion failed: (!stream->blocking).
- lib-compression: bench-compress crashes due to xz being read-only.
- lib-lua: Fix linking libdict_lua for non-GNU linkers when Lua support
  is disabled.
- lib-mail: There was no limit on how large an email header name could be.
  Processable header names are now limited to 1000 bytes.
- lib-oauth2: Dovecot disallowed JWT tokens if their validity time was
  older than token creation time (nbf < iat).
- lib-storage: Reduce memory footprint of certain storage operations.
- lib-storage: When listing mailboxes with storage name escape
  characters (^ or .) as part of the mailbox name, the listing could
  show corrupted mailbox names. Due to an issue in handling escaped
  parent folders, the listing of other mailbox names would become
  corrupted by prepending parts of the previously listed mailboxes
  parent folder as prefix to the actual mailbox names. The corruption
  can occur when using LAYOUT=INDEX and maildir or obox, or when using
  the listescape plugin.
- mail-crypt: Fix "-O" argument for "doveadm mailbox cryptokey password"
  command to be a boolean, and not expect a string.
- submission-login: Add support for not authenticating to next hop in
  submission proxying.
- submission-login: EHLO was not sent again after XCLIENT when doing
  submission proxying.
- virtual: Mailboxes do not correctly detect underlying mailboxes
  getting re-created even though they have a different UIDVALIDITY or
  GUID.

mail/dovecot: update to 2.3.15

Security release.

v2.3.15 2021-06-21  Aki Tuomi <aki.tuomi@open-xchange.com>

* CVE-2021-29157: Dovecot does not correctly escape kid and azp fields in
  JWT tokens. This may be used to supply attacker controlled keys to
  validate tokens, if attacker has local access.
* CVE-2021-33515: On-path attacker could have injected plaintext commands
  before STARTTLS negotiation that would be executed after STARTTLS
  finished with the client.
* Disconnection log messages are now more standardized across services.
  They also always now start with "Disconnected" prefix.
* Dovecot now depends on libsystemd for systemd integration.
* Removed support for Lua 5.2. Use version 5.1 or 5.3 instead.
* config: Some settings are now marked as "hidden". It's discouraged to
  change these settings. They will no longer be visible in doveconf
  output, except if they have been changed or if doveconf -s parameter
  is used. See https://doc.dovecot.org/settings/advanced/ for details.
* imap-compress: Compression level is now algorithm specific.
  See https://doc.dovecot.org/settings/plugin/compress-plugin/
* indexer-worker: Convert "Indexed" info logs to an event named
  "indexer_worker_indexing_finished". See
  https://doc.dovecot.org/admin_manual/list_of_events/#indexer-worker-indexing-finished
+ Add TSLv1.3 support to min_protocols.
+ Allow configuring ssl_cipher_suites. (for TLSv1.3+)
+ acl: Add acl_ignore_namespace setting which allows to entirely ignore
  ACLs for the listed namespaces.
+ imap: Support official RFC8970 preview/snippet syntax. Old methods of
  retrieving preview information via IMAP commands ("SNIPPET and PREVIEW
  with explicit algorithm selection") have been deprecated.
+ imapc: Support INDEXPVT for imapc storage to enable private
  message flags for cluster wide shared mailboxes.
+ lib-storage: Add new events: mail_opened, mail_expunge_requested,
  mail_expunged, mail_cache_lookup_finished. See
  https://doc.dovecot.org/admin_manual/list_of_events/#mail
+ zlib, imap-compression, fs-compress: Support compression levels that
  the algorithm supports. Before, we would allow hardcoded value between
  1 to 9 and would default to 6. Now we allow using per-algorithm value
  range and default to whatever default the algorithm specifies.
- *-login: Commands pipelined together with and just after the authenticate
  command cause these commands to be executed twice. This applies to all
  protocols that involve user login, which currently comprises of imap,
  pop3, submisision and managesieve.
- *-login: Processes are supposed to disconnect the oldest non-logged in
  connection when process_limit was reached. This didn't actually happen
  with the default "high-security mode" (with service_count=1) where each
  connection is handled by a separate process.
- *-login: When login process reaches client/process limits, oldest
  client connections are disconnected. If one of these was still doing
  anvil lookup, this caused a crash. This could happen only if the login
  process limits were very low or if the server was overloaded.
- Fixed building with link time optimizations (-flto).
- auth: Userdb iteration with passwd driver does not always return all
  users with some nss drivers.
- dsync: Shared INBOX not synced when "mail_shared_explicit_inbox" was
  disabled. If a user has a shared mailbox which is another user's INBOX,
  dsync didn't include the mailbox in syncing unless explicit naming is
  enabled with "mail_shared_explicit_inbox" set to "yes".
- dsync: Shared namespaces were not synced with "-n" flag.
- dsync: Syncing shared INBOX failed if mail_attribute_dict was not set.
  If a user has a shared mailbox that is another user's INBOX, dsync
  failed to export the mailbox if mail attributes are disabled.
- fts-solr, fts-tika: Using both Solr FTS and Tika may have caused HTTP
  requests to assert-crash: Panic: file http-client-request.c: line 1232
  (http_client_request_send_more): assertion failed: (req->payload_input != NULL)
- fts-tika: 5xx errors returned by Tika server as indexing failures.
  However, Tika can return 5xx for some attachments every time.
  So the 5xx error should be retried once, but treated as success if it
  happens on the retry as well. v2.3 regression.
- fts-tika: v2.3.11 regression: Indexing messages with fts-tika may have
  resulted in Panic: file message-parser.c: line 802 (message_parser_deinit_from_parts):
  assertion failed: (ctx->nested_parts_count == 0 || i_stream_have_bytes_left(ctx->input))
- imap: SETMETADATA could not be used to unset metadata values.
  Instead NIL was handled as a "NIL" string. v2.3.14 regression.
- imap: IMAP BINARY FETCH crashes at least on empty base64 body:
  Panic: file index-mail-binary.c: line 358 (blocks_count_lines):
  assertion failed: (block_count == 0 || block_idx+1 == block_count)
- imap: If IMAP client using the NOTIFY command was disconnected while
  sending FETCH notifications to the client, imap could crash with
  Panic: Trying to close mailbox INBOX with open transactions.
- imap: Using IMAP COMPRESS extension can cause IMAP connection to hang
  when IMAP commands are >8 kB long.
- imapc: If remote server sent BYE but didn't immediately disconnect, it
  could cause infinite busy-loop.
- lib-index: Corrupted cache record size in dovecot.index.cache file
  could have caused a crash (segfault) when accessing it.
- lib-oauth2: JWT token time validation now works correctly with
  32-bit systems.
- lib-ssl-iostream: Checking hostnames against an SSL certificate was
  case-sensitive.
- lib-storage: Corrupted mime.parts in dovecot.index.cache may have
  resulted in Panic: file imap-bodystructure.c: line 206 (part_write_body):
  assertion failed: (text == ((part->flags & MESSAGE_PART_FLAG_TEXT) != 0))
- lib-storage: Index rebuilding (e.g. via doveadm force-resync) didn't
  preserve the "hdr-pop3-uidl" header. Because of this, the next pop3
  session could have accessed all of the emails' metadata to read their
  POP3 UIDL (opening dbox files).
- listescape: When using the listescape plugin and a shared namespace
  the plugin didn't work properly anymore resulting in errors like:
  "Invalid mailbox name: Name must not have '/' character."
- lmtp: Connection crashes if connection gets disconnected due to
  multiple bad commands and the last bad command is BDAT.
- lmtp: The Dovecot-specific LMTP parameter XRCPTFORWARD was blindly
  forwarded by LMTP proxy without checking that the backend has support.
  This caused a command parameter error from the backend if it was
  running an older Dovecot release. This could only occur in more complex
  setups where the message was proxied twice; when the proxy generated
  the XRCPTFORWARD parameter itself the problem did not occur, so this
  only happened when it was forwarded.
- lmtp: The LMTP proxy crashes with a panic when the remote server
  replies with an error while the mail is still being forwarded through
  a DATA/BDAT command.
- lmtp: Username may have been missing from lmtp log line prefixes when
  it was performing autoexpunging.
- master: Dovecot would incorrectly fail with haproxy 2.0.14 service
  checks.
- master: Systemd service: Dovecot announces readiness for accepting
  connections earlier than it should. The following environment variables
  are now imported automatically and can be omitted from
  import_environment setting: NOTIFY_SOCKET LISTEN_FDS LISTEN_PID.
- master: service { process_min_avail } was launching processes too
  slowly when master was forking a lot of processes.
- util: Make the health-check.sh example script POSIX shell compatible.

mail/dovecot2: update to 2.3.14

From release announce:

	We have removed some components from the software, please
	review changelogs carefully prior upgrading.


V2.3.14 2021-03-04  Aki Tuomi <aki.tuomi@open-xchange.com>

* Added new aliases for some variables. Usage of the old ones is possible,
  but discouraged. (These were partially added already to v2.3.13.)
  See https://doc.dovecot.org/configuration_manual/config_file/config_variables/
  for more information.
* Optimize imap/pop3/submission/managesieve proxies to use less CPU at
  the cost of extra memory usage.
* Remove autocreate, expire, snarf and mail-filter plugins.
* Remove cydir storage driver.
* Remove XZ/LZMA write support. Read support will be removed in future release.
* doveadm -D: Add timestamps to debug output even when LOG_STDERR_TIMESTAMP
  environment variable is not set. Timestamp format is taken from
  log_timestamp setting.
* If BROKENCHAR or listescape plugin is used, the escaped folder names
  may be slightly different from before in some situations. This is
  unlikely to cause issues, although caching clients may redownload the
  folders.
* imapc: It now enables BROKENCHAR=~ by default to escape remote folder
  names if necessary. This also means that if there are any '~'
  characters in the remote folder names, they will be visible as "~7e".
* imapc: When using local index files folder names were escaped on
  filesystem a bit differently. This affects only if there are folder
  names that actually require escaping, which isn't so common. The old
  style folders will be automatically deleted from filesystem.
* stats: Update exported metrics to be compliant with OpenMetrics standard.
+ doveadm: Add an optional '-p' parameter to metadata list command. If
  enabled, "/private", and "/shared" metadata prefixes will be prepended
  to the keys in the list output.
+ doveconf: Support environment variables in config files. See
  https://doc.dovecot.org/configuration_manual/config_file/config_file_syntax/#environment-variables
  for more details.
+ indexer-worker: Change indexer to disconnect from indexer-worker
  after each request. This allows service indexer-worker's service_count &
  idle_kill settings to work. These can be used to restart indexer-worker
  processes once in a while to reduce their memory usage.
- auth: "nodelay" with various authentication mechanisms such as apop
  and digest-md5 crashed AUTH process if authentication failed.
- auth: Auth lua script generating an error triggered an assertion
  failure: Panic: file db-lua.c: line 630 (auth_lua_call_password_verify):
  assertion failed: (lua_gettop(script->L) == 0).
- configure: Fix libunwind detection to work on other than x86_64 systems.
- doveadm-server: Process could crash if logging was done outside command
  handling. For example http-client could have done debug logging
  afterwards, resulting in either segfault or Panic:
  file http-client.c: line 642 (http_client_context_close):
  assertion failed: (cctx->clients_list == NULL).
- dsync: Folder name escaping with BROKENCHAR didn't work completely
  correctly. This especially caused problems with dsync-migrations using
  imapc where some of the remote folder names may not have been accessible.
- dsync: doveadm sync + imapc doesn't always sync all mails when doing
  an incremental sync (-1), which could lead to mail loss when it's used
  for migration. This happens only when GUIDs aren't used (i.e.
  imapc without imapc_features=guid-forced).
- fts-tika: When tika server returns error, some mails cause Panic:
  file message-parser.c: line 802 (message_parser_deinit_from_parts):
  assertion failed: (ctx->nested_parts_count == 0 || i_stream_have_bytes_left(ctx->input))
- lib-imap: imapc parsing illegal BODYSTRUCTUREs with NILs could have
  resulted in crashes. This exposed that Dovecot was wrongly accepting
  atoms in "nstring" handling. Changed the IMAP parsing to be more
  strict about this now.
- lib-index: If dovecot.index.cache has corrupted message size, fetching
  BODY/BODYSTRUCTURE may cause assert-crash:
  Panic: file index-mail.c: line 1140 (index_mail_parse_body_finish):
  assertion failed: (mail->data.parts != NULL).
- lib-index: Minor error handling and race condition fixes related to
  rotating dovecot.index.log. These didn't usually cause problems,
  unless the log files were rotated rapidly.
- lib-lua: Lua scripts using coroutines or lua libraries using coroutines
  (e.g., cqueues) panicked.
- Message PREVIEW handled whitespace wrong so first space would get
  eaten from between words.
- FTS and message PREVIEW (snippet) parsed HTML &entities case-sensitively.
- lib-mail: When max nested MIME parts were reached, IMAP BODYSTRUCTURE
  was written in a way that may have caused confusion for IMAP clients
  and also Dovecot itself when parsing it. The truncated part is now

   v2.3.13 2021-01-04	Aki Tuomi <aki.tuomi@open-xchange.com>

   	* CVE-2020-24386: Specially crafted command can cause IMAP hibernate to
   	  allow logged in user to access other people's emails and filesystem
   	  information.
   	* Metric filter and global event filter variable syntax changed to a
   	  SQL-like format. See https://doc.dovecot.org/configuration_manual/event_filter/
   	* auth: Added new aliases for %{variables}. Usage of the old ones is
   	  possible, but discouraged.
   	* auth: Removed RPA auth mechanism, SKEY auth mechanism, NTLM auth
   	  mechanism and related password schemes.
   	* auth: Removed passdb-sia, passdb-vpopmail and userdb-vpopmail.
   	* auth: Removed postfix postmap socket
   	+ auth: Added new fields for auth server events. These fields are now
   	  also available for all auth events. See
   	  https://doc.dovecot.org/admin_manual/list_of_events/#authentication-server
   	  for details.
   	+ imap-hibernate: Added imap_client_hibernated, imap_client_unhibernated
   	  and imap_client_unhibernate_retried events. See
   	  https://doc.dovecot.org/admin_manual/list_of_events/ for details.
   	+ lib-index: Added new mail_index_recreated event. See
   	  https://doc.dovecot.org/admin_manual/list_of_events/#mail-index-recreated
   	+ lib-sql: Support TLS options for cassandra driver. This requires
   	  cpp-driver v2.15 (or later) to work reliably.
   	+ lib-storage: Missing $HasAttachment / $HasNoAttachment flags are now
   	  added to existing mails if mail_attachment_detection_option=add-flags
   	  and it can be done inexpensively.
   	+ login proxy: Added login_proxy_max_reconnects setting (default 3) to
   	  control how many reconnections are attempted.
   	+ login proxy: imap/pop3/submission/managesieve proxying now supports
   	  reconnection retrying on more than just connect() failure. Any error
   	  except a non-temporary authentication failure will result in reconnect
   	  attempts.
   	- auth: Lua passdb/userdb leaks stack elements per call, eventually
   	  causing the stack to become too deep and crashing the auth or
   	  auth-worker process.
   	- auth: SASL authentication PLAIN mechanism could be used to trigger
   	  read buffer overflow. However, this doesn't seem to be exploitable in
   	  any way.
   	- auth: v2.3.11 regression: GSSAPI authentication fails because dovecot
   	  disallows NUL bytes for it.
   	- dict: Process used too much CPU when iterating keys, because each key
   	  used a separate write() syscall.
   	- doveadm-server: Crash could occur if logging was done outside command
   	  handling. For example http-client could have done debug logging
   	  afterwards, resulting in either segfault or
   	  Panic: file http-client.c: line 642 (http_client_context_close):
   	  assertion failed: (cctx->clients_list == NULL).
   	- doveadm-server: v2.3.11 regression: Trying to connect to doveadm server
   	  process via starttls assert-crashed if there were no ssl=yes listeners:
   	  Panic: file master-service-ssl.c: line 22 (master_service_ssl_init):
   	  assertion failed: (service->ssl_ctx_initialized).
   	- fts-solr: HTTP requests may have assert-crashed:
   	  Panic: file http-client-request.c: line 1232 (http_client_request_send_more):
   	  assertion failed: (req->payload_input != NULL)
   	- imap: IMAP NOTIFY could crash with a segmentation fault due to a bad
   	  configuration that causes errors. Sending the error responses to the
   	  client can cause the segmentation fault. This can for example happen
   	  when several namespaces use the same mail storage location.
   	- imap: IMAP NOTIFY used on a shared namespace that doesn't actually
   	  exist (e.g. public namespace for a nonexistent user) can crash with a panic:
   	  Panic: Leaked view for index /tmp/home/asdf/mdbox/dovecot.list.index: Opened in (null):0
   	- imap: IMAP session can crash with QRESYNC extension if many changes
   	  are done before asking for expunged mails since last sync.
   	- imap: Process might hang indefinitely if client disconnects after
   	  sending some long-running commands pipelined, for example FETCH+LOGOUT.
   	- lib-compress: Mitigate crashes when configuring a not compiled in
   	  compression. Errors with compression configuration now distinguish
   	  between not supported and unknown.
   	- lib-compression: Using xz/lzma compression in v2.3.11 could have
   	  written truncated output in some situations. This would result in
   	  "Broken pipe" read errors when trying to read it back.
   	- lib-compression: zstd compression could have crashed in some situations:
   	  Panic: file ostream.c: line 287 (o_stream_sendv_int): assertion failed: (!stream->blocking)
   	- lib-dict: dict client could have crashed in some rare situations when
   	  iterating keys.
   	- lib-http: Fix several assert-crashes in HTTP client.
   	- lib-index: v2.3.11 regression: When mails were expunged at the same
   	  time as lots of new content was being saved to the cache (e.g. cache
   	  file was lost and is being re-filled) a deadlock could occur with
   	  dovecot.index.cache / dovecot.index.log.
   	- lib-index: v2.3.11 regression: dovecot.index.cache file was being
   	  purged (rewritten) too often when it had a field that hadn't been
   	  accessed for over 1 month, but less than 2 months. Every cache file
   	  change caused a purging in this situation.
   	- lib-mail: MIME parts were not returned correctly by Dovecot MIME parser.
   	  Regression caused by fixing CVE-2020-12100.
   	- lib-mail: When max nested MIME parts were reached, IMAP BODYSTRUCTURE
   	  was written in a way that may have caused confusion for both IMAP
   	  clients and Dovecot itself when parsing it. The truncated part is now
   	  written out using application/octet-stream MIME type.
   	- lib-mail: v2.3.11 regression: Mail delivery / parsing crashed when the
   	  10000th MIME part was message/rfc822 (or if parent was multipart/digest):
   	  Panic: file message-parser.c: line 167 (message_part_append):
   	  assertion failed: (ctx->total_parts_count <= ctx->max_total_mime_parts).
   	- lib-oauth2: Dovecot incorrectly required oauth2 server introspection
   	  reply to contain username with invalid token.
   	- lib-ssl-iostream, lib-dcrypt: Fix building with OpenSSL that has
   	  deprecated APIs disabled.
   	- lib-storage: When mail's size is different from the cached one (in
   	  dovecot.index.cache or Maildir S=size in the filename), this is
   	  handled by logging "Cached message size smaller/larger than expected"
   	  error. However, in some situations this also ended up crashing with:
   	  Panic: file istream.c: line 315 (i_stream_read_memarea):
   	  assertion failed: (old_size <= _stream->pos - _stream->skip).
   	- lib-storage: v2.3 regression: Copying/moving mails was taking much more
   	  memory than before. This was mainly visible when copying/moving
   	  thousands of mails in a single transaction.
   	- lib-storage: v2.3.11 regression: Searching messages assert-crashed
   	  (without FTS): Panic: file message-parser.c: line 174 (message_part_finish):
   	  assertion failed: (ctx->nested_parts_count > 0).
   	- lib: Dovecot v2.3 moved signal handlers around in ioloops,
   	  causing more CPU usage than in v2.2.
   	- lib: Fixed JSON parsing: '\' escape sequence may have wrongly resulted
   	  in error if it happened to be at read boundary. Any NUL characters and
   	  '\u0000' will now result in parsing error instead of silently
   	  truncating the data.
   	- lmtp, submission: Server may hang if SSL client connection disconnects
   	  during the delivery. If this happened repeated, it could have ended
   	  up reaching process_limit and preventing any further lmtp/submission
   	  deliveries.
   	- lmtp: Proxy does not always properly log TLS connection problems as
   	  errors; in some cases, only a debug message is logged if enabled.
   	- lmtp: The LMTP service can hang when commands are pipelined. This can
   	  particularly occur when one command in the middle of the pipeline fails.
   	  One example of this occurs for proxied LMTP transactions in which the
   	  final DATA or BDAT command is pipelined after a failing RCPT command.
   	- login-proxy: The login_source_ips setting has no effect, and therefore
   	  the proxy source IPs are not cycled through as they should be.
   	- master: Process was using 100% CPU in some situations when a broken
   	  service was being throttled.
   	- pop3-login: POP3 login would fail with "Input buffer full" if the
   	  initial response for SASL was too long.
   	- stats: Crash would occur when generating openmetrics data for metrics
   	  using aggregating functions.

           - pop3-login: Login didn't handle commands in multiple IP packets properly.

   v2.3.11 2020-06-17  Aki Tuomi <aki.tuomi@open-xchange.com>

           * CVE-2020-12100: Parsing mails with a large number of MIME parts could
             have resulted in excessive CPU usage or a crash due to running out of
             stack memory.
           * CVE-2020-12673: Dovecot's NTLM implementation does not correctly check
             message buffer size, which leads to reading past allocation which can
             lead to crash.
           * CVE-2020-12674: Dovecot's RPA mechanism implementation accepts
             zero-length message, which leads to assert-crash later on.
           * Events: Fix inconsistency in events. See event documentation in
             https://doc.dovecot.org.
           * imap_command_finished event's cmd_name field now contains "unknown"
             for unknown commands. A new "cmd_input_name" field contains the
             command name exactly as it was sent.
           * lib-index: Renamed mail_cache_compress_* settings to mail_cache_purge_*.
             Note that these settings are mainly intended for testing and usually
             shouldn't be changed.
           * events: Renamed "index" event category to "mail-index".
           * events: service:<name> category is now using the name from
             configuration file.
           * dns-client: service dns_client was renamed to dns-client.
           * log: Prefixes generally use the service name from configuration file.
             For example dict-async service will now use

mail/dovocot2: update to 2.3.11.3

Update dovecot2 and related packages to 2.3.11.3.

v2.3.11.3 2020-07-29	Aki Tuomi <aki.tuomi@open-xchange.com>

	- pop3-login: Login didn't handle commands in multiple IP packets properly.
	  This mainly affected large XCLIENT commands or a large SASL initial
	  response parameter in the AUTH command.
	- pop3: pop3_deleted_flag setting was broken, causing:
	  Panic: file seq-range-array.c: line 472 (seq_range_array_invert):
	  assertion failed: (range[count-1].seq2 <= max_seq)

v2.3.11.2 2020-07-13	Aki Tuomi <aki.tuomi@open-xchange.com>

	- auth: Lua passdb/userdb leaks stack elements per call, eventually
	  causing the stack to become too deep and crashing the auth or
	  auth-worker process.
	- lib-mail: v2.3.11 regression: MIME parts not returned correctly by
	  Dovecot MIME parser.
	- pop3-login: Login would fail with "Input buffer full" if the initial
	  response for SASL was too long.

v2.3.11 2020-06-17  Aki Tuomi <aki.tuomi@open-xchange.com>

	* CVE-2020-12100: Parsing mails with a large number of MIME parts could
	  have resulted in excessive CPU usage or a crash due to running out of
	  stack memory.
	* CVE-2020-12673: Dovecot's NTLM implementation does not correctly check
	  message buffer size, which leads to reading past allocation which can
	  lead to crash.
	* CVE-2020-12674: Dovecot's RPA mechanism implementation accepts
	  zero-length message, which leads to assert-crash later on.
	* Events: Fix inconsistency in events. See event documentation in
	  https://doc.dovecot.org.
	* imap_command_finished event's cmd_name field now contains "unknown"
	  for unknown commands. A new "cmd_input_name" field contains the
	  command name exactly as it was sent.
	* lib-index: Renamed mail_cache_compress_* settings to mail_cache_purge_*.
	  Note that these settings are mainly intended for testing and usually
	  shouldn't be changed.
	* events: Renamed "index" event category to "mail-index".
	* events: service:<name> category is now using the name from
	  configuration file.
	* dns-client: service dns_client was renamed to dns-client.
	* log: Prefixes generally use the service name from configuration file.
	  For example dict-async service will now use
	  "dict-async(pid): " log prefix instead of "dict(pid): "
	* *-login: Changed logging done by proxying to use a consistent prefix
	  containing the IP address and port.

dovecot2: updated to 2.3.10

v2.3.10
* Disable retpoline migitations by default. These can cause severe
  performance regressions, so they should be only enabled when
  applicable.
* IMAP MOVE now commits transactions in batches of 1000 mails. This
  helps especially with lazy_expunge when moving a lot of mails. It
  mainly avoids situations where multiple IMAP sessions are running the
  same MOVE command and duplicating the mails in the lazy_expunge folder.
  With this change there can still be some duplication, but the MOVE
  always progresses forward. Also if the MOVE fails at some point, the
  changes up to the last 1000 mails are still committed instead of
  rolled back. Note that the COPY command behavior hasn't changed,
  because it is required by IMAP standard to be an atomic operation.
* IMAP EXPUNGE and CLOSE now expunges mails in batches of 1000 mails.
  This helps especially with lazy_expunge when expunging a lot of mails
  (e.g. millions) to make sure that the progress always moves forward
  even if the process is killed.
* Autoexpunging now expunges mails in batches of 1000 mails. This helps
  especially with lazy_expunge when expunging a lot of mails
  (e.g. millions) to make sure that the progress always moves forward
  even if the process is killed.
+ Add tool for generating sysreport called dovecot-sysreport.
  This generates a bundle of information usually needed for support
  requests.
+ Add support for the new IMAP \Important SPECIAL-USE flag (RFC 8457).
+ Add metric { group_by } setting. This allows automatically creating
  new metrics based on the fields you want to group statistics by.
  NOTE: This feature is considered experimental and syntax is subject
  to change in future release.
+ auth: Support SCRAM-SHA-256 authentication mechanism.
+ imap: Support the new IMAP STATUS=SIZE extension.
+ Use TCP_QUICKACK to reduce latency for some TCP connections.
+ quota-status: Made the service more robust against erroneous use with
  Postfix ACL policies other than smtpd_recipient_restrictions.
+ Add "revision" field support to imap_id_send setting. Using
  "revision *" will send in IMAP ID command response the short commit
  hash of the Dovecot git source tree HEAD (same as in dovecot --version).
+ IMAP ENVELOPE includes now all addresses when there are multiple
  headers (From, To, Cc, etc.) The standard way of having multiple
  addresses is to just list them all in a single header. It's
  non-standard to have multiple headers. However, since MTAs allow these
  mails to pass through and different software may handle them in
  different ways, it's better from security point of view to show all
  the addresses.
+ Event filters now support using "field_name=" to match a field that
  doesn't exist or has an empty value. For example use "error=" to match
  only events that didn't fail.
- acl: INBOX ACLs shouldn't apply for IMAP GETMETADATA/SETMETADATA
  commands.
- cassandra: CASS_ERROR_SERVER_WRITE_FAILURE error should also be
  treated as "uncertain write failure".
- dict-redis: Using quota_clone configured with dict-redis could have
  crashed when Redis responded slowly.
- imap-hibernate: Communication trouble with imap-master leads to
  segfault.
- imap-hibernate: Unhibernation retrying wasn't working.
- imap: Fixed auth lookup privilege problem when imap process was reused
  and user was being un-hibernated.
- Fix potential crash when copying/moving mails within the same folder.
  This happened only when there were a lot of fields in dovecot.index.cache.
- lib-index: Recreating dovecot.index.cache file could have crashed when
  merging bitmask fields.
- lib-index: Using public/shared folders with INDEXPVT configured to use
  private \Seen flags, trying to search seen/unseen in an empty folder
  crashes with segfault.
- lib-mail: Large base64-encoded mails weren't decoded properly.
  This could have affected searching/indexing mails and message snippet
  generation.
- lib-mail: Message with only quoted text could have caused message
  snippet to ignore its 200 character limit and return the entire
  message. This was added also to dovecot.index.cache file, which
  increased disk space and memory usage unnecessarily.
  v2.3.9.2 regression (previous versions cached the quoted snippet as
  empty). In a large mail quoted text could have become wrongly added
  to the snippet, possibly mixed together with non-quoted text.
- lib-smtp: client could have assert-crashed if STARTTLS handshake
  finished earlier than usually.
- lib-ssl-iostream: remove -static flag for lib-ssl-iostream linking to
  prevent a compile issue.
- lib-storage: Mailbox synchronization may have assert-crashed in some
  rare situations.
- lib-storage: mdbox didn't preserve date.saved with dsync.
- lib: Don't require EAI_{ADDRFAMILY,NODATA}, breaks FreeBSD
- master: Some services could respawn unthrottled if they crash during
  startup.
- push-notification: Do not send push_notification_finished event if
  nothing was done. This happens when mail transaction is started and
  ended with no changes.
- quota-status: Addresses with special characters in the local part caused
  problems in the interaction between Postfix and Dovecot. Postfix sent
  its own internal representation in the recipient field, while Dovecot
  expected a valid RFC5321 mailbox address.
- submission-login: SESSION was not correctly encoded field for the
  XCLIENT command. Particularly, a '+' character introduced by the
  session ID's Base64 encoding causes problems.
- submission: Fix submission_max_mail_size to work correctly on 32-bit
  systems.
- submission: Trusted connections crashed in second connection's EHLO
  if submission-login { service_count } is something else than 1 (which
  is the default).
- submission: XCLIENT command was never used in the protocol exchange
  with the relay MTA when submission_backend_capabilities is configured,
  even when the relay MTA was properly configured to accept the XCLIENT
  command.

dovecot2: updated to 2.3.9

v2.3.9:
* Changed several event field names for consistency and to avoid
  conflicts in parent-child event relationships:
   * SMTP server command events: Renamed "name" to "cmd_name"
   * Events inheriting from a mailbox: Renamed "name" to "mailbox"
   * Server connection events have only "remote_ip", "remote_port",
     "local_ip" and "local_port".
   * Removed duplicate "client_ip", "ip" and "port".
   * Mail storage events: Removed "service" field.
     Use "service:<name>" category instead.
   * HTTP client connection events: Renamed "host" to "dest_host" and
     "port" to "dest_port"
* auth: Drop Postfix socketmap support. It hasn't been working
  with recent Postfix versions for a while now.
* push-notification-lua: The "subject" field is now decoded to UTF8
  instead of kept as MIME-encoded.
+ push-notification-lua: Added new "from_address", "from_display_name",
  "to_address" and "to_display_name" fields. The display names are
  decoded to UTF8.
+ Added various new fields to existing events.
  See http://doc.dovecot.net/admin_manual/list_of_events.html
+ Add lmtp_add_received_header setting. It can be used to prevent LMTP
  from adding "Received:" headers.
+ doveadm: Support SSL/STARTTLS for proxied doveadm connections based on
  doveadm_ssl setting and proxy ssl/tls settings.
+ Log filters support now "service:<name>", which matches all events for
  the given service. It can also be used as a category.
+ lib: Use libunwind to get abort backtraces with function names
  where available.
+ lmtp: When the LMTP proxy changes the username (from passdb lookup)
  add an appropriate ORCPT parameter.
- lmtp: Add lmtp_client_workarounds setting to implement workarounds for
  clients that send MAIL and RCPT commands with additional spaces before
  the path and for clients that omit <> brackets around the path.
  See example-config/conf.d/20-lmtp.conf.
- lda/lmtp: Invalid MAIL FROM addresses were rejcted too aggressively.
  Now mails from addresses with unicode characters are delivered, but
  their Return-Path header will be <> instead of the given MAIL FROM
  address.
- lmtp: The lmtp_hdr_delivery_address setting is ignored.
- imap: imap_command_finished event's "args" and "human_args" parameters
  were always empty.
- mbox: Seeking in zlib and bzip2 compressed input streams didn't work
  correctly.
- imap-hibernate: Process crashed when client got destroyed while it was
  attempted to be unhibernated, and the unhibernation fails.
- *-login: Proxying may have crashed if SSL handshake to the backend
  failed immediately. This was unlikely to happen in normal operation.
- *-login: If TLS handshake to upstream server failed during proxying,
  login process could crash due to invalid memory access.
- *-login: v2.3 regression: Using SASL authentication without initial
  response may have caused SSL connections to hang. This happened often
  at least with PHP's IMAP library.
- *-login: When login processes are flooded with authentication attempts
  it starts logging errors about "Authentication server sent unknown id".
  This is still expected. However, it also caused the login process to
  disconnect from auth server and potentially log some user's password
  in the error message.
- dict-sql: SQL prepared statements were not shared between sessions.
  This resulted in creating a lot of prepared statements, which was
  especially inefficient when using Cassandra backend with a lot of
  Cassandra nodes.
- auth: auth_request_finished event didn't have success=yes parameter
  set for successful authentications.
- auth: userdb dict - Trying to list users crashed.
- submission: Service could be configured to allow anonymous
  authentication mechanism and anonymous user access.
- LAYOUT=index: Corrupted dovecot.list.index caused folder creation to
  panic.
- doveadm: HTTP server crashes if request target starts with double "/".
- dsync: Remote dsync started hanging if the initial doveadm
  "dsync-server" command was sent in the same TCP packet as the
  following dsync handshake. v2.3.8 regression.
- lib: Several "input streams" had a bug that in some rare situations
  might cause it to access freed memory. This could lead to crashes or
  corruption.
  The only currently known effect of this is that using zlib plugin with
  external mail attachments (mail_attachment_dir) could cause fetching
  the mail to return a few bytes of garbage data at the beginning of the
  header. Note that the mail wasn't saved corrupted, but fetching it
  caused corrupted mail to be sent to the client.
- lib-storage: If a mail only has quoted content, use the quoted text
  for generating message snippet (IMAP PREVIEW) instead of returning
  empty snippet.
- lib-storage: When vsize header was rebuilt, newly calculated message
  sizes were added to dovecot.index.cache instead of being directly
  saved into vsize records in dovecot.index.
- lib: JSON generator was escaping UTF-8 characters unnecessarily.

mail/dovecot2: update to 2.3.8

Update dovecot2 and friends to 2.3.8.

2.3.8 2019-10-08

Changes

+ Added mail_delivery_started and mail_delivery_finished events, see
  https://doc.dovecot.org/admin_manual/list_of_events/ for details.
+ dsync-replication: Don't replicate users who have "noreplicate" extra
  field in userdb.
+ doveadm service status: Show total number of processes created.
+ When logging to syslog, use instance_name setting's value for the
  ident. This commonly is added as a log prefix.
+ Base64 encoding/decoding code was rewritten with additional features.
  It shouldn't cause any user visible changes.
- v2.3.7 regression: If a folder only receives new mails without any
  other mail access, dovecot.index.log keeps growing forever and
  dovecot.index keeps being rewritten for every mail delivery.
- dsync-replication may lose keywords after syncing mails restored from
  another replica. This only happened if the mail only had keywords and no
  system flags.
- event filters: Non-textual event fields could not be filtered using
  wildcards.
- auth: Scope parameter was missing from OAuth password grant request.
- doveadm client-server communication may hang in some situations. It is
  also using unnecessarily small TCP/IP packet sizes.
- doveadm who and kick did not flush protocol output correctly.
- imap: SETMETADATA with literal value would delete the metadata value
  instead of updating it.
- imap: When client issues FETCH PREVIEW (LAZY=FUZZY) command, the
  caching decisions should be updated so that newly saved mails will have
  the preview cached.
- With mail_nfs_index=yes and/or mail_nfs_storage=yes setuid/setgid
  permission bits in some files may have become dropped with some NFS
  servers. Changed NFS flushing to now use chmod() instead of chown().
- quota: warnings did not work if quota root was noenforcing
- acl: Global ACL file ignored the last line if it didn't end with LF.
- doveadm stats dump: With JSON formatter output numbers using the
  number type instead of as strings
- lmtp_proxy: Ensure that real_* variables are correctly set when using
  lmtp_proxy.
- event exporter: http-post driver had hardcoded timeout and did not
  support DNS lookups or TLS connections.
- auth: Fix user iteration to work with userdb passwd with glibc v2.28.
- auth: auth service can crash if auth-policy JSON response is invalid
  or returned too fast.
- In some rare situations "ps" output could have shown a lot of "?"
  characters after Dovecot process titles.
- When dovecot.index.pvt is empty, an unnecessary error is logged:
  Error: .../dovecot.index.pvt reset, view is now inconsistent
- SMTP address encoder duplicated initial double quote character when
  the localpart of an address ended in '..'. For example
  "user+..@example.com" became ""user+.."@example.com in a
  sieve redirect.

   + Added more events for the new statistics, see
     https://doc.dovecot.org/admin_manual/list_of_events/
   + mail-lua: Add IMAP metadata accessors, see
     https://doc.dovecot.org/admin_manual/lua/
   + Add event exporters that allow exporting raw events to log files and
     external systems, see
     https://doc.dovecot.org/configuration_manual/event_export/
   + SNIPPET is now PREVIEW and size has been increased to 200 characters.
   + Add body option to fts_enforced. This triggers building FTS index only
     on body search, and an error using FTS index fails the search rather
     than reads through all the mails.
   - Submission/LMTP: Fixed crash when domain argument is invalid in a
     second EHLO/LHLO command.
   - Copying/moving mails using Maildir format loses IMAP keywords in the
     destination if the mail also has no system flags.
   - mail_attachment_detection_options=3Dadd-flags-on-save caused email body
     to be unnecessarily opened when FETCHing mail headers that were
     already cached.
   - mail attachment detection keywords not saved with maildir.
   - dovecot.index.cache may have grown excessively large in some
     situations. This happened especially when using autoexpunging with
     lazy_expunge folders. Also with mdbox format in general the cache file
     wasn't recreated as often as it should have.
   - Autoexpunged mails weren't immediately deleted from the disk. Instead,
     the deletion from disk happened the next time the folder was opened.
     This could have caused unnecessary delays if the opening was done by
     an interactive IMAP session.
   - Dovecot's TCP connections sometimes add extra 40ms latency due to not
     enabling TCP_NODELAY. HTTP and SMTP/LMTP connections weren't
     affected, but everything else was. This delay wasn't always visible -
     only in some situations with some message/packet sizes.
   - imapc: Fix various crash conditions
   - Dovecot builds were not always reproducible.
   - login-proxy: With shutdown_clients=3Dno after config reload the
     existing connections could no longer be listed or kicked with doveadm.
   - "doveadm proxy kick" with -f parameter caused a crash in some
     situations.
   - Auth policy can cause segmentation fault crash during auth process
     shutdown if all auth requests have not been finished.
   - Fix various minor bugs leading into incorrect behaviour in mailbox
     list index handling. These rarely caused noticeable problems.
   - LDAP auth: Iteration accesses freed memory, possibly crashing
     auth-worker
   - local_name { .. } filter in dovecot.conf does not correctly support
     multiple names and wildcards were matched incorrectly.
   - replicator: dsync assert-crashes if it can't connect to remote TCP
     server.
   - config: Memory leak in config process when ssl_dh setting wasn't
     set and there was no ssl-parameters.dat file.
     This caused config process to die once in a while
     with "out of memory".

Update mail/dovecot2 to v2.3.5.

From the upstream release-note:

NEWS:

+ Lua push notification driver: mail keywords and flags are provided
in MessageNew and MessageAppend events.
+ submission: Implement support for plugins.
+ auth: When auth_policy_log_only=yes, only log what the policy server
response would do without actually doing it.
+ auth: Always log policy server decisions with auth_verbose=yes
- v2.3.[34]: doveadm log errors: Output was missing user/session
- lda: Debug log lines could have shown slightly corrupted
- login proxy: Login processes may have crashed in various ways when
login_proxy_max_disconnect_delay was set.
- imap: Fix crash with Maildir+zlib if client disconnects during APPEND
- lmtp proxy: Fix potential assert-crash
- lmtp/submission: Fix crash when SMTP client transaction times out
- submission: Split large XCLIENT commands to 512 bytes per command,

token (e.g. via stopwords).

dovecot2: updated to 2.3.4

2.3.4:
 * The default postmaster_address is now "postmaster@<user domain or
   server hostname>". If username contains the @domain part, that's
   used. If not, then the server's hostname is used.
 * "doveadm stats dump" now returns two decimals for the "avg" field.

 + Added push notification driver that uses a Lua script
 + Added new SQL, DNS and connection events.
   See https://wiki2.dovecot.org/Events
 + Added "doveadm mailbox cache purge" command.
 + Added events API support for Lua scripts
 + doveadm force-resync -f parameter performs "index fsck" while opening
   the index. This may be useful to fix some types of broken index files.
   This may become the default behavior in a later version.
 - director: Kicking a user crashes if login process is very slow
 - pop3_no_flag_updates=no: Don't expunge DELEted and RETRed messages
   unless QUIT is sent.
 - auth: Fix crypt() segfault with glibc-2.28+
 - imap: Running UID FILTER script with errors assert-crashes
 - dsync, pop3-migration: POP3 UIDLs weren't added to
   dovecot.index.cache while mails were saved.
 - dict clients may have been using 100% CPU while waiting for dict
   server to finish commands.
 - doveadm user: Fixed user listing via HTTP API
 - All levels of Cassandra log messages were logged as Dovecot errors.
 - http/smtp client may have crashed after SSL handshake
 - Lua auth converted strings that looked like numbers into numbers.

dovecot2: updated to 2.3.3

2.3.3:
* doveconf hides more secrets now in the default output.
* ssl_dh setting is no longer enforced at startup. If it's not set and
  non-ECC DH key exchange happens, error is logged and client is
  disconnected.

+ Added log_debug=<filter> setting.
+ Added log_core_filter=<log filter> setting.
+ quota-clone: Write to dict asynchronously
+ --enable-hardening attempts to use retpoline Spectre 2 mitigations
+ lmtp proxy: Support source_ip passdb extra field.
+ doveadm stats dump: Support more fields and output stddev by default.
+ push-notification: Add SSL support for OX backend.
- NUL bytes in mail headers can cause truncated replies when fetched.
- director: Conflicting host up/down state changes may in some rare
  situations ended up in a loop of two directors constantly overwriting
  each others' changes.

  handled concurrently.
- director: Fix assert-crash if doveadm disconnects too early
- virtual plugin: Some searches used 100% CPU for many seconds
- dsync assert-crashed with acl plugin in some situations.
- mail_attachment_detection_options=add-flags-on-save assert-crashed
  with some specific Sieve scripts.
- Mail snippet generation crashed with mails containing invalid
  Content-Type:multipart header.
- Log prefix ordering was different for some log lines.
- quota: With noenforcing option current quota usage wasn't updated.
- auth: Kerberos authentication against Samba assert-crashed.
- stats clients were unnecessarily chatty with the stats server.
- imapc: Fixed various assert-crashes when reconnecting to server.
- lmtp, submission: Fix potential crash if client disconnects while
  handling a command.
- quota: Fixed compiling with glibc-2.26 / support libtirpc.
- fts-solr: Empty search values resulted in 400 Bad Request errors
- fts-solr: default_ns parameter couldn't be used
- submission server crashed if relay server returned over 7 lines in
  a reply (e.g. to EHLO)

dovecot2: updated to 2.3.2.1

v2.3.2 still had a few unexpected bugs:
- SSL/TLS servers may have crashed during client disconnection
- lmtp: With lmtp_rcpt_check_quota=yes mail deliveries may have
  sometimes assert-crashed.
- v2.3.2: "make check" may have crashed with 32bit systems

v2.3.2 is mainly a bugfix release. It contains all the changes in v2.2.36, as well as a bunch of other fixes (mainly for v2.3-only bugs). Binary packages are already in https://repo.dovecot.org/
* old-stats plugin: Don't temporarily enable PR_SET_DUMPABLE while
  opening /proc/self/io. This may still cause security problems if the
  process is ptrace()d at the same time. Instead, open it while still
  running as root.
+ doveadm: Added mailbox cache decision&remove commands. See
  doveadm-mailbox(1) man page for details.
+ doveadm: Added rebuild attachments command for rebuilding
  $HasAttachment or $HasNoAttachment flags for matching mails. See

+ lmtp: Add lmtp_rawlog_dir and lmtp_proxy_rawlog_dir settings.
+ submission: Add support for rawlog_dir
+ submission: Add submission_client_workarounds setting.
+ lua auth: Add password_verify() function and additional fields in
  auth request.
- doveadm-server: TCP connections are hanging when there is a lot of
  network output. This especially caused hangs in dsync-replication.
- Using multiple type=shared mdbox namespaces crashed
- mail_fsync setting was ignored. It was always set to "optimized".
- lua auth: Fix potential crash at deinit
- SSL/TLS servers may have crashed if client disconnected during
  handshake.
- SSL/TLS servers: Don't send extraneous certificates to client when
  alt certs are used.
- lda, lmtp: Return-Path header without '<' may have assert-crashed.
- lda, lmtp: Unencoded UTF-8 in email address headers may assert-crash
- lda: -f parameter didn't allow empty/null/domainless address
- lmtp, submission: Message size limit was hardcoded to 40 MB.
  Exceeding it caused the connection to get dropped during transfer.
- lmtp: Fix potential crash when delivery fails at DATA stage
- lmtp: login_greeting setting was ignored
- Fix to work with OpenSSL v1.0.2f
- systemd unit restrictions were too strict by default
- Fix potential crashes when a lot of log output was produced
- SMTP client may have assert-crashed when sending mail
- IMAP COMPRESS: Send "end of compression" marker when disconnecting.
- cassandra: Fix consistency=quorum to work
- dsync: Lock file generation failed if home directory didn't exist

  reconnection all mails in the selected mailbox are gone.
- pop3c: Handle unexpected server disconnections without assert-crash
- fts: Fixes to indexing mails via virtual mailboxes.
- fts: If mails contained NUL characters, the text around it wasn't
  indexed.
- Obsolete dovecot.index.cache offsets were sometimes used. Trying to
  fetch a field that was just added to cache file may not have always
  found it.

dovecot2: update to 2.3.1

Changes:
* Submission server support improvements and bug fixes
  - Lots of bug fixes to submission server
* API CHANGE: array_idx_modifiable will no longer allocate space
 - Particularly affects how you should check MODULE_CONTEXT result, or use REQUIRE_MODULE_CONTEXT.

+ mail_attachment_detection_options setting controls when
  $HasAttachment and $HasNoAttachment keywords are set for mails.
+ imap: Support fetching body snippets using FETCH (SNIPPET) or
  (SNIPPET (LAZY=FUZZY))
+ fs-compress: Automatically detect whether input is compressed or not.
  Prefix the compression algorithm with "maybe-" to enable the
  detection, for example: "compress:maybe-gz:6:..."
+ Added settings to change dovecot.index* files' optimization behavior.
  See https://wiki2.dovecot.org/IndexFiles#Settings
+ Auth cache can now utilize auth workers to do password hash
  verification by setting auth_cache_verify_password_with_worker=yes.
+ Added charset_alias plugin. See
  https://wiki2.dovecot.org/Plugins/CharsetAlias
+ imap_logout_format and pop3_logout_format settings now support all of the generic variables (e.g. %{rip}, %{session}, etc.)

   Log Message:
   Update mail/dovecot2* to 2.3.0.

   Some of the larger changes:

   * Various setting changes, see https://wiki2.dovecot.org/Upgrading/2.3
   * Logging rewrite started: Logging is now based on hierarchical events.
     This makes it possible to do various things, like: 1) giving
     consistent log prefixes, 2) enabling debug logging with finer
     granularity, 3) provide logs in more machine readable formats
     (e.g. json). Everything isn't finished yet, especially a lot of the
     old logging code still needs to be translated to the new way.
   * Statistics rewrite started: Stats are now based on (log) events.
     It's possible to gather statistics about any event that is logged.
     See http://wiki2.dovecot.org/Statistics for details
   * ssl_dh setting replaces the old generated ssl-parameters.dat
   * IMAP: When BINARY FETCH finds a broken mails, send [PARSE] error
     instead of [UNKNOWNCTE]
   * Linux: core dumping via PR_SET_DUMPABLE is no longer enabled by
     default due to potential security reasons (found by cPanel Security
     Team).
   + Added support for SMTP submission proxy server, which includes
     support for BURL and CHUNKING extension.
   + LMTP rewrite. Supports now CHUNKING extension and mixing of
     local/proxy recipients.
   + auth: Support libsodium to add support for ARGON2I and ARGON2ID
     password schemes.
   + auth: Support BLF-CRYPT password scheme in all platforms
   + auth: Added LUA scripting support for passdb/userdb.
     See https://wiki2.dovecot.org/AuthDatabase/Lua
   - Input streams are more reliable now when there are errors or when
     the maximum buffer size is reached. Previously in some situations
     this could have caused Dovecot to try to read already freed memory.
   - Output streams weren't previously handling failures when writing a
     trailer at the end of the stream. This mainly affected encrypt and
     zlib compress ostreams, which could have silently written truncated
     files if the last write happened to fail (which shouldn't normally
     have ever happened).
   - virtual plugin: Fixed panic when fetching mails from virtual
     mailboxes with IMAP BINARY extension.
   - doveadm-server: Fix potential hangs with SSL connections
   - doveadm proxy: Reading commands' output from v2.2.33+ servers could

   mail/dovecot2: update to 2.3.0.1

   Small patch release to fix the worst bugs in v2.3.0. v2.3.1 is coming in about a month with a lot more changes.

    * CVE-2017-15130: TLS SNI config lookups may lead to excessive
      memory usage, causing imap-login/pop3-login VSZ limit to be reached
      and the process restarted. This happens only if Dovecot config has

      randomly generated SNI servernames.
    * CVE-2017-14461: Parsing invalid email addresses may cause a crash or
      leak memory contents to attacker. For example, these memory contents
      might contain parts of an email from another user if the same imap
      process is reused for multiple users. First discovered by Aleksandar
      Nikolic of Cisco Talos. Independently also discovered by "flxflndy"

      chroot/group restrictions. Found by cPanel Security Team. Nowadays
      core dumps can be safely enabled by using "sysctl -w

Update mail/dovecot2* to 2.3.0.

Some of the larger changes:

* Various setting changes, see https://wiki2.dovecot.org/Upgrading/2.3
* Logging rewrite started: Logging is now based on hierarchical events.
  This makes it possible to do various things, like: 1) giving
  consistent log prefixes, 2) enabling debug logging with finer
  granularity, 3) provide logs in more machine readable formats
  (e.g. json). Everything isn't finished yet, especially a lot of the
  old logging code still needs to be translated to the new way.
* Statistics rewrite started: Stats are now based on (log) events.
  It's possible to gather statistics about any event that is logged.
  See http://wiki2.dovecot.org/Statistics for details
* ssl_dh setting replaces the old generated ssl-parameters.dat
* IMAP: When BINARY FETCH finds a broken mails, send [PARSE] error
  instead of [UNKNOWNCTE]
* Linux: core dumping via PR_SET_DUMPABLE is no longer enabled by
  default due to potential security reasons (found by cPanel Security
  Team).
+ Added support for SMTP submission proxy server, which includes
  support for BURL and CHUNKING extension.
+ LMTP rewrite. Supports now CHUNKING extension and mixing of
  local/proxy recipients.
+ auth: Support libsodium to add support for ARGON2I and ARGON2ID
  password schemes.
+ auth: Support BLF-CRYPT password scheme in all platforms
+ auth: Added LUA scripting support for passdb/userdb.
  See https://wiki2.dovecot.org/AuthDatabase/Lua
- Input streams are more reliable now when there are errors or when
  the maximum buffer size is reached. Previously in some situations
  this could have caused Dovecot to try to read already freed memory.
- Output streams weren't previously handling failures when writing a
  trailer at the end of the stream. This mainly affected encrypt and
  zlib compress ostreams, which could have silently written truncated
  files if the last write happened to fail (which shouldn't normally
  have ever happened).
- virtual plugin: Fixed panic when fetching mails from virtual
  mailboxes with IMAP BINARY extension.
- doveadm-server: Fix potential hangs with SSL connections
- doveadm proxy: Reading commands' output from v2.2.33+ servers could
  have caused the output to be corrupted or caused a crash.
- Many other smaller fixes

dovecot2: update to 2.2.33.1

v2.2.33.1:
- dovecot-lda was logging to stderr instead of to the log file.

v2.2.33:
* doveadm director commands wait for the changes to be visible in the
  whole ring before they return. This is especially useful in testing.
* Environments listed in import_environment setting are now set or
  preserved when executing standalone commands (e.g. doveadm)

+ doveadm proxy: Support proxying logs. Previously the logs were
  visible only in the backend's logs.
+ Added %{if}, see https://wiki2.dovecot.org/Variables#Conditionals
+ Added a new notify_status plugin, which can be used to update dict
  with current status of a mailbox when it changes. See
  https://wiki2.dovecot.org/Plugins/NotifyStatus
+ Mailbox list index can be disabled for a namespace by appending
  ":LISTINDEX=" to location setting.
+ dsync/imapc: Added dsync_hashed_headers setting to specify which
  headers are used to match emails.
+ pop3-migration: Add pop3_migration_ignore_extra_uidls=yes to ignore
  mails that are visible in POP3 but not IMAP. This could happen if
  new mails were delivered during the migration run.
+ pop3-migration: Further improvements to help with Zimbra
+ pop3-migration: Cache POP3 UIDLs in imapc's dovecot.index.cache
  if indexes are enabled. These are used to optimize incremental syncs.
+ cassandra, dict-sql: Use prepared statements if protocol version>3.
+ auth: Added %{ldap_dn} variable for passdb/userdb ldap
- acl: The "create" (k) permission in global acl-file was sometimes
  ignored, allowing users to create mailboxes when they shouldn't have.
- sdbox: Mails were always opened when expunging, unless
  mail_attachment_fs was explicitly set to empty.
- lmtp/doveadm proxy: hostip passdb field was ignored, which caused
  unnecessary DNS lookups if host field wasn't an IP
- lmtp proxy: Fix crash when receiving unexpected reply in RCPT TO
- quota_clone: Update also when quota is unlimited (broken in v2.2.31)
- mbox, zlib: Fix assert-crash when accessing compressed mbox
- doveadm director kick -f parameter didn't work
- doveadm director flush <host> resulted flushing all hosts, if <host>
  wasn't an IP address.
- director: Various fixes to handling backend/director changes at
  abnormal times, especially while ring was unsynced. These could have
  resulted in crashes, non-optimal behavior or ignoring some of the
  changes.
- director: Use less CPU in imap-login processes when moving/kicking
  many users.
- lmtp: Session IDs were duplicated/confusing with multiple RCPT TOs
  when lmtp_rcpt_check_quota=yes
- doveadm sync -1 fails when local mailboxes exist that do not exist
  remotely. This commonly happened when lazy_expunge mailbox was
  autocreated when incremental sync expunged mails.
- pop3: rawlog_dir setting didn't work

Changes 2.2.32:
There are various changes in this release that can be used to significantly reduce disk IO with:
1) NFS storage especially, but I guess also other remote filesystems and even some with local disks
2) When mail storage and INDEX storage are separated

 * imapc: Info-level line is logged every time when successfully
   connected to the remote server. This includes local/remote IP/port,
   which can be useful for matching against external logs.
 * config: Log a warning if plugin { key=no } is used explicitly.
   v2.3 will support "no" properly in plugin settings, but for now
   any value at all for a boolean plugin setting is treated as "yes",
   even if it's written as explicit "no". This change will now warn
   that it most likely won't work as intended.

 + Various optimizations to avoid accessing files/directories when it's
   not necessary. Especially avoid accessing mail root directories when
   INDEX directories point to a different filesystem.
 + mail_location can now include ITERINDEX parameter. This tells Dovecot
   to perform mailbox listing from the INDEX path instead of from the
   mail root path. It's mainly useful when the INDEX storage is on a
   faster storage.
 + mail_location can now include VOLATILEDIR=<path> parameter. This
   is used for creating lock files and in future potentially other
   files that don't need to exist permanently. The path could point to
   tmpfs for example. This is especially useful to avoid creating lock
   files to NFS or other remote filesystems. For example:
   mail_location=sdbox:~/sdbox:VOLATILEDIR=/tmp/volatile/%2.256Nu/%u
 + mail_location's LISTINDEX=<path> can now contain a full path.
   This allows storing mailbox list index to a different storage
   than the rest of the indexes, for example to tmpfs.
 + mail_location can now include NO-NOSELECT parameter. This
   automatically deletes any \NoSelect mailboxes that have no children.
   These mailboxes are sometimes confusing to users.
 + mail_location can now include BROKENCHAR=<char> parameter. This can
   be useful with imapc to access mailbox names that aren't valid mUTF-7
   charset from remote servers.
 + If mailbox_list_index_very_dirty_syncs=yes, the list index is no
   longer refreshed against filesystem when listing mailboxes. This
   allows the mailbox listing to be done entirely by only reading the
   mailbox list index.
 + Added mailbox_list_index_include_inbox setting to control whether
   INBOX's STATUS information should be cached in the mailbox list
   index. The default is "no", but it may be useful to change it to
   "yes", especially if LISTINDEX points to tmpfs.
 + userdb can return chdir=<path>, which override mail_home for the
   chdir location. This can be useful to avoid accessing home directory
   on login.
 + userdb can return postlogin=<socket> to specify per-user imap/pop3
   postlogin socket path.
 + cassandra: Add support for result paging by adding page_size=<n>
   parameter to the connect setting.
 + dsync/imapc, pop3-migration plugin: Strip also trailing tabs from
   headers when matching mails. This helps with migrations from Zimbra.
 + imap_logout_format supports now %{appended} and %{autoexpunged}
 + virtual plugin: Optimize IDLE to use mailbox list index for finding
   out when something has changed.
 + Added apparmor plugin. See https://wiki2.dovecot.org/Plugins/Apparmor
 - virtual plugin: A lot of fixes. In many cases it was also working
   very inefficiently or even incorrectly.
 - imap: NOTIFY parameter parsing was incorrectly "fixed" in v2.2.31.
   It was actually (mostly) working in previous versions, but broken
   in v2.2.31.
 - Modseq tracking didn't always work correctly. This could have caused
   imap unhibernation to fail or IMAP QRESYNC/CONDSTORE extensions to
   not work perfectly.
 - mdbox: "Inconsistency in map index" wasn't fixed automatically
 - dict-ldap: %variable values used in the LDAP filter weren't escaped.
 - quota=count: quota_warning = -storage=.. was never executed (try 2).
   v2.2.31 fixed it for -messages, but not for -storage.
 - imapc: >= 32 kB mail bodies were supposed to be cached for subsequent
   FETCHes, but weren't.
 - quota-status service didn't support recipient_delimiter
 - acl: Don't access dovecot-acl-list files with acl_globals_only=yes
 - mail_location: If INDEX dir is set, mailbox deletion deletes its
   childrens' indexes. For example if "box" is deleted, "box/child"
   index directory was deleted as well (but mails were preserved).
 - director: v2.2.31 caused rapid reconnection loops to directors
   that were down.

Changes 2.2.31:
* LMTP: Removed "(Dovecot)" from added Received headers. Some
  installations want to hide it, and there's not really any good reason
  for anyone to have it.

+ Add ssl_alt_cert and ssl_alt_key settings to add support for
  having both RSA and ECDSA certificates.
+ dsync/imapc, pop3-migration plugin: Strip trailing whitespace from
  headers when matching mails. This helps with migrations from Zimbra.
+ acl: Add acl_globals_only setting to disable looking up
  per-mailbox dovecot-acl files.
+ Parse invalid message addresses better. This mainly affects the
  generated IMAP ENVELOPE replies.
- v2.2.30 wasn't fixing corrupted dovecot.index.cache files properly.
  It could have deleted wrong mail's cache or assert-crashed.
- v2.2.30 mail-crypt-acl plugin was assert-crashing
- v2.2.30 welcome plugin wasn't working
- Various fixes to handling mailbox listing. Especially related to
  handling nonexistent autocreated/autosubscribed mailboxes and ACLs.
- Global ACL file was parsed as if it was local ACL file. This caused
  some of the ACL rule interactions to not work exactly as intended.
- auth: forward_* fields didn't work properly: Only the first forward
  field was working, and only if the first passdb lookup succeeded.
- Using mail_sort_max_read_count sometimes caused "Broken sort-*
  indexes, resetting" errors.
- Using mail_sort_max_read_count may have caused very high CPU usage.
- Message address parsing could have crashed on invalid input.
- imapc_features=fetch-headers wasn't always working correctly and
  caused the full header to be fetched.
- imapc: Various bugfixes related to connection failure handling.
- quota=imapc sent unnecessary FETCH RFC822.SIZE to server when
  expunging mails.
- quota=count: quota_warning = -storage=.. was never executed
- quota=count: Add support for "ns" parameter
- dsync: Fix incremental syncing for mails that don't have Date or
  Message-ID headers.
- imap: Fix hang when client sends pipelined SEARCH +
  EXPUNGE/CLOSE/LOGOUT.
- oauth2: Token validation didn't accept empty server responses.
- imap: NOTIFY command has been almost completely broken since the
  beginning. I guess nobody has been trying to use it.

Changes 2.2.30:
* auth: Use timing safe comparisons for everything related to
  passwords. It's unlikely that these could have been used for
  practical attacks, especially because Dovecot delays and flushes all
  failed authentications in 2 second intervals. Also it could have
  worked only when passwords were stored in plaintext in the passdb.
* master process sends SIGQUIT to all running children at shutdown,
  which instructs them to close all the socket listeners immediately.
  This way restarting Dovecot should no longer fail due to some
  processes keeping the listeners open for a long time.

+ auth: Add passdb { mechanisms=none } to match separate passdb lookup
+ auth: Add passdb { username_filter } to use passdb only if user
  matches the filter. See https://wiki2.dovecot.org/PasswordDatabase
+ dsync: Add dsync_commit_msgs_interval setting. It attempts to commit
  the transaction after saving this many new messages. Because of the
  way dsync works, it may not always be possible if mails are copied
  or UIDs need to change.
+ imapc: Support imapc_features=search without ESEARCH extension.
+ imapc: Add imapc_features=fetch-bodystructure to pass through remote
  server's FETCH BODY and BODYSTRUCTURE.
+ imapc: Add quota=imapc backend to use GETQUOTA/GETQUOTAROOT on the
  remote server.
+ passdb imap: Add allow_invalid_cert and ssl_ca_file parameters.
+ If dovecot.index.cache corruption is detected, reset only the one
  corrupted mail instead of the whole file.
+ doveadm mailbox status: Add "firstsaved" field.
+ director_flush_socket: Add old host's up/down and vhost count as parameters
- More fixes to automatically fix corruption in dovecot.list.index
- dsync-server: Fix support for dsync_features=empty-header-workaround
- imapc: Various bugfixes, including infinite loops on some errors
- IMAP NOTIFY wasn't working for non-INBOX if IMAP client hadn't
  enabled modseq tracking via CONDSTORE/QRESYNC.
- fts-lucene: Fix it to work again with mbox format
- Some internal error messages may have contained garbage in v2.2.29
- mail-crypt: Re-encrypt when copying/moving mails and per-mailbox keys
  are used. Otherwise the copied mails can't be opened.
- vpopmail: Fix compiling

   Update dovecot2 to 2.2.29.1.  This release contains security fixes.

   v2.2.29.1 2017-04-12  Timo Sirainen <tss@iki.fi>

   	- imapc reconnection fix was forgotten from 2.2.29 release, which also
   	  made "make check" fail in a unit test
   	- dict-sql: Merging multiple UPDATEs to a single statement wasn't
   	  actually working.
   	- Fixed building with vpopmail

   v2.2.29 2017-04-10  Timo Sirainen <tss@iki.fi>

   	* passdb/userdb dict: Don't double-expand %variables in keys. If dict
   	  was used as the authentication passdb, using specially crafted
   	  %variables in the username could be used to cause DoS (CVE-2017-2669)
   	* When Dovecot encounters an internal error, it logs the real error and
   	  usually logs another line saying what function failed. Previously the
   	  second log line's error message was a rather uninformative "Internal
   	  error occurred. Refer to server log for more information." Now the
   	  real error message is duplicated in this second log line.
   	* lmtp: If a delivery has multiple recipients, run autoexpunging only
   	  for the last recipient. This avoids a problem where a long
   	  autoexpunge run causes LMTP client to timeout between the DATA
   	  replies, resulting in duplicate mail deliveries.
   	* config: Don't stop the process due to idling. Otherwise the
   	  configuration is reloaded when the process restarts.
   	* mail_log plugin: Differentiate autoexpunges from regular expunges
   	* imapc: Use LOGOUT to cleanly disconnect from server.
   	* lib-http: Internal status codes (>9000) are no longer visible in logs
   	* director: Log vhost count changes and HOST-UP/DOWNte autoexpunges from regular expunges
   	* imapc: Use LOGOUT to cleanly disconnect from server.
   	* lib-http: Internal status codes (>9000) are no longer visible in logs
   	* director: Log vhost count changes and HOST-UP/DOWN

   + quota: Add plugin { quota_max_mail_size } setting to limit the
   	  maximum individual mail size that can be saved.
   	+ imapc: Add imapc_features=delay-login. If set, connecting to the
   	  remote IMAP server isn't done until it's necessary.
   	+ imapc: Add imapc_connection_retry_count and
   	  imapc_connection_retry_interval settings.
   	+ imap, pop3, indexer-worker: Add (deinit) to process title before
   	  autoexpunging runs.
   + Added %{encrypt} and %{decrypt} variables
   	+ imap/pop3 proxy: Log proxy state in errors as human-readable string.
   	+ imap/pop3-login: All forward_* extra fields returned by passdb are
   	  sent to the next hop when proxying using ID/XCLIENT commands. On the
   	  receiving side these fields are imported and sent to auth process
   	  where they're accessible via %{passdb:forward_*}. This is done only
   	  if the sending IP address matches login_trusted_networks.
   	+ imap-login: If imap_id_retain=yes, send the IMAP ID string to
   	  auth process. %{client_id} expands to it in auth process. The ID
   	  string is also sent to the next hop when proxying.
   	+ passdb imap: Use ssl_client_ca_* settings for CA validation.
   	- fts-tika: Fixed crash when parsing attachment without
   	  Content-Disposition header. Broken by 2.2.28.
   	- trash plugin was broken in 2.2.28
   	- auth: When passdb/userdb lookups were done via auth-workers, too much
   	  data was added to auth cache. This could have resulted in wrong
   	  replies when using multiple passdbs/userdbs.
   	- auth: passdb { skip & mechanisms } were ignored for the first passdb
   	- oauth2: Various fixes, including fixes to crashes
   	- dsync: Large Sieve scripts (or other large metadata) weren't always
   	  synced.
   - Index rebuild (e.g. doveadm force-resync) set all mails as \Recent
   	- imap-hibernate: %{userdb:*} wasn't expanded in mail_log_prefix
   	- doveadm: Exit codes weren't preserved when proxying commands via
   	  doveadm-server. Almost all errors used exit code 75 (tempfail).
   	- ACLs weren't applied to not-yet-existing autocreated mailboxes.
   	- Fixed a potential crash when parsing a broken message header.
   	- cassandra: Fallback consistency settings weren't working correctly.
   	- doveadm director status <user>: "Initial config" was always empty
   	- imapc: Various reconnection fixes.

	  for the last recipient. This avoids a problem where a long
	  autoexpunge run causes LMTP client to timeout between the DATA
	  replies, resulting in duplicate mail deliveries.
	* config: Don't stop the process due to idling. Otherwise the
	  configuration is reloaded when the process restarts.
	* mail_log plugin: Differentiate autoexpunges from regular expunges
	* imapc: Use LOGOUT to cleanly disconnect from server.
	* lib-http: Internal status codes (>9000) are no longer visible in logs
	* director: Log vhost count changes and HOST-UP/DOWN

	+ quota: Add plugin { quota_max_mail_size } setting to limit the
	  maximum individual mail size that can be saved.
	+ imapc: Add imapc_features=delay-login. If set, connecting to the
	  remote IMAP server isn't done until it's necessary.
	+ imapc: Add imapc_connection_retry_count and
	  imapc_connection_retry_interval settings.
	+ imap, pop3, indexer-worker: Add (deinit) to process title before
	  autoexpunging runs.
	+ Added %{encrypt} and %{decrypt} variables
	+ imap/pop3 proxy: Log proxy state in errors as human-readable string.
	+ imap/pop3-login: All forward_* extra fields returned by passdb are
	  sent to the next hop when proxying using ID/XCLIENT commands. On the
	  receiving side these fields are imported and sent to auth process
	  where they're accessible via %{passdb:forward_*}. This is done only
	  if the sending IP address matches login_trusted_networks.
	+ imap-login: If imap_id_retain=yes, send the IMAP ID string to
	  auth process. %{client_id} expands to it in auth process. The ID
	  string is also sent to the next hop when proxying.
	+ passdb imap: Use ssl_client_ca_* settings for CA validation.
	- fts-tika: Fixed crash when parsing attachment without
	  Content-Disposition header. Broken by 2.2.28.
	- trash plugin was broken in 2.2.28
	- auth: When passdb/userdb lookups were done via auth-workers, too much
	  data was added to auth cache. This could have resulted in wrong
	  replies when using multiple passdbs/userdbs.
	- auth: passdb { skip & mechanisms } were ignored for the first passdb
	- oauth2: Various fixes, including fixes to crashes
	- dsync: Large Sieve scripts (or other large metadata) weren't always
	  synced.
	- Index rebuild (e.g. doveadm force-resync) set all mails as \Recent
	- imap-hibernate: %{userdb:*} wasn't expanded in mail_log_prefix
	- doveadm: Exit codes weren't preserved when proxying commands via
	  doveadm-server. Almost all errors used exit code 75 (tempfail).
	- ACLs weren't applied to not-yet-existing autocreated mailboxes.
	- Fixed a potential crash when parsing a broken message header.
	- cassandra: Fallback consistency settings weren't working correctly.
	- doveadm director status <user>: "Initial config" was always empty
	- imapc: Various reconnection fixes.

Changes 2.2.28:
* director: "doveadm director move" to same host now refreshes user's
  timeout. This allows keeping user constantly in the same backend by
  just periodically moving the user there.
* When new mailbox is created, use initially INBOX's
  dovecot.index.cache caching decisions.
* Expunging mails writes GUID to dovecot.index.log now only if the
  GUID is quickly available from index/cache.
* pop3c: Increase timeout for PASS command to 5 minutes.
* Mail access errors are no longer ignored when searching or sorting.
  With IMAP the untagged SEARCH/SORT reply is still sent the same as
  before, but NO reply is returned instead of OK.

+ Make dovecot.list.index's filename configurable. This is needed when
  there are multiple namespaces pointing to the same mail root
  (e.g. lazy_expunge namespace for mdbox).
+ Add size.virtual to dovecot.index when folder vsizes are accessed
  (e.g. quota=count). This is mainly a workaround to avoid slow quota
  recalculation performance when message sizes get lost from
  dovecot.index.cache due to corruption or some other reason.
+ auth: Support OAUTHBEARER and XOAUTH2 mechanisms. Also support them
  in lib-dsasl for client side.
+ auth: Support filtering by SASL mechanism: passdb { mechanisms }
+ Shrink the mail processes' memory usage by not storing settings
  duplicated unnecessarily many times.
+ imap: Add imap_fetch_failure setting to control what happens when
  FETCH fails for some mails (see example-config).
+ imap: Include info about last command in disconnection log line.
+ imap: Created new SEARCH=X-MIMEPART extension. It's currently not
  advertised by default, since it's not fully implemented.
+ fts-solr: Add support for basic authentication.
+ Cassandra: Support automatically retrying failed queries if
  execution_retry_interval and execution_retry_times are set.
+ doveadm: Added "mailbox path" command.
+ mail_log plugin: If plugin { mail_log_cached_only=yes }, log the
  wanted fields only if it doesn't require opening the email.
+ mail_vsize_bg_after_count setting added (see example-config).
+ mail_sort_max_read_count setting added (see example-config).
+ pop3c: Added pop3c_features=no-pipelining setting to prevent using
  PIPELINING extension even though it's advertised.

- Index files: day_first_uid wasn't updated correctly since v2.2.26.
  This caused dovecot.index.cache to be non-optimal.
- imap: SEARCH/SORT may have assert-crashed in
  client_check_command_hangs
- imap: FETCH X-MAILBOX may have assert-crashed in virtual mailboxes.
- imap: Running time in tagged command reply was often wrongly 0.
- search: Using NOT n:* or NOT UID n:* wasn't handled correctly
- director: doveadm director kick was broken
- director: Fix crash when using director_flush_socket
- director: Fix some bugs when moving users between backends
- imapc: Various error handling fixes and improvements
- master: doveadm process status output had a lot of duplicates.
- autoexpunge: If mailbox's rename timestamp is newer than mail's
  save-timestamp, use it instead. This is useful when autoexpunging
  e.g. Trash/* and an entire mailbox is deleted by renaming it under
  Trash to prevent it from being autoexpunged too early.
- autoexpunge: Multiple processes may have been trying to expunge the
  same mails simultaneously. This was problematic especially with
  lazy_expunge plugin.
- auth: %{passdb:*} was empty in auth-worker processes
- auth-policy: hashed_password was always sent empty.
- dict-sql: Merge multiple UPDATEs to a single statement if possible.
- fts-solr: Escape {} chars when sending queries
- fts: fts_autoindex_exclude = \Special-use caused crashes
- doveadm-server: Fix leaks and other problems when process is reused
  for multiple requests (service_count != 1)
- sdbox: Fix assert-crash on mailbox create race
- lda/lmtp: deliver_log_format values weren't entirely correct if Sieve
  was used. especially %{storage_id} was broken.
- lmtp_user_concurrency_limit didn't work if userdb changed username

Changes 2.2.27:
* dovecot.list.index.log rotation sizes/times were changed so that
  the .log file stays smaller and .log.2 is deleted sooner.
+ Added mail_crypt plugin that allows encryption of stored emails.
  See http://wiki2.dovecot.org/Plugins/MailCrypt
+ stats: Global stats can be sent to Carbon server by setting
  stats_carbon_server=ip:port
+ imap/pop3 proxy: If passdb returns proxy_not_trusted, don't send
  ID/XCLIENT
+ Added generic hash modifier for %variables:
  %{<hash algorithm>;rounds=<n>,truncate=<bits>,salt=s>:field}
  Hash algorithm is any of the supported ones, e.g. md5, sha1, sha256.
  Also "pkcs5" is supported using SHA256. For example: %{sha256:user}
  or %{md5;truncate=32:user}.
+ Added support for SHA3-256 and SHA3-512 hashes.
+ config: Support DNS wildcards in local_name, e.g.
  local_name *.example.com { .. } matches anything.example.com, but
  not multiple.anything.example.com.
+ config: Support multiple names in local_name, e.g.
  local_name "1.example.com 2.example.com" { .. }
- Fixed crash in auth process when auth-policy was configured and
  authentication was aborted/failed without a username set.
- director: If two users had different tags but the same hash,
  the users may have been redirected to the wrong tag's hosts.
- Index files may have been thought incorrectly lost, causing
  "Missing middle file seq=.." to be logged and index rebuild.
  This happened more easily with IMAP hibernation enabled.
- Various fixes to restoring state correctly in un-hibernation.
- dovecot.index files were commonly 4 bytes per email too large. This
  is because 3 bytes per email were being wasted that could have been
  used for IMAP keywords.
- Various fixes to handle dovecot.list.index corruption better.
- lib-fts: Fixed assert-crash in address tokenizer with specific input.
- Fixed assert-crash in HTML to text parsing with specific input
  (e.g. for FTS indexing or snippet generation)
- doveadm sync -1: Fixed handling mailbox GUID conflicts.
- sdbox, mdbox: Perform full index rebuild if corruption is detected
  inside lib-index, which runs index fsck.
- quota: Don't skip quota checks when moving mails between different
  quota roots.
- search: Multiple sequence sets or UID sets in search parameters
  weren't handled correctly. They were incorrectly merged together.

Add build problem on NetBSD 7.0_STABLE at least.

Changes 2.2.26:
 * master: Removed hardcoded 511 backlog limit for listen(). The kernel
   should limit this as needed.
 * doveadm import: Source user is now initialized the same as target
   user. Added -U parameter to override the source user.
 * Mailbox names are no longer limited to 16 hierarchy levels. We'll
   check another way to make sure mailbox names can't grow larger than
   4096 bytes.

 + Added a concept of "alternative usernames" by returning user_* extra
   field(s) in passdb. doveadm proxy list shows these alt usernames in
   "doveadm proxy list" output. "doveadm director&proxy kick" adds
   -f <passdb field> parameter. The alt usernames don't have to be
   unique, so this allows creation of user groups and kicking them in
   one command.
 + auth: passdb/userdb dict allows now %variables in key settings.
 + auth: If passdb returns noauthenticate=yes extra field, assume that
   it only set extra fields and authentication wasn't actually performed.
 + auth: passdb static now supports password={scheme} prefix.
 + auth, login_log_format_elements: Added %{local_name} variable, which
   expands to TLS SNI hostname if given.
 + imapc: Added imapc_max_line_length to limit maximum memory usage.
 + imap, pop3: Added rawlog_dir setting to store IMAP/POP3 traffic logs.
   This replaces at least partially the rawlog plugin.
 + dsync: Added dsync_features=empty-header-workaround setting. This
   makes incremental dsyncs work better for servers that randomly return
   empty headers for mails. When an empty header is seen for an existing
   mail, dsync assumes that it matches the local mail.
 + doveadm sync/backup: Added -I <max size> parameter to skip too
   large mails.
 + doveadm sync/backup: Fixed -t parameter and added -e for "end date".
 + doveadm mailbox metadata: Added -s parameter to allow accessing
   server metadata by using empty mailbox name.
 + Added "doveadm service status" and "doveadm process status" commands.
 + director: Added director_flush_socket. See
   http://wiki2.dovecot.org/Director#Flush_socket
 + doveadm director flush: Users are now moved only max 100 at a time to
   avoid load spikes. --max-parallel parameter overrides this.
 + Added FILE_LOCK_SLOW_WARNING_MSECS environment, which logs a warning
   if any lock is waited on or kept for this many milliseconds.

 - master process's listener socket was leaked to all child processes.
   This might have allowed untrusted processes to capture and prevent
   "doveadm service stop" comands from working.
 - login proxy: Fixed crash when outgoing SSL connections were hanging.
 - auth: userdb fields weren't passed to auth-workers, so %{userdb:*}
   from previous userdbs didn't work there.
 - auth: Each userdb lookup from cache reset its TTL.
 - auth: Fixed auth_bind=yes + sasl_bind=yes to work together
 - auth: Blocking userdb lookups reset extra fields set by previous
   userdbs.
 - auth: Cache keys didn't include %{passdb:*} and %{userdb:*}
 - auth-policy: Fixed crash due to using already-freed memory if policy
   lookup takes longer than auth request exists.
 - lib-auth: Unescape passdb/userdb extra fields. Mainly affected
   returning extra fields with LFs or TABs.
 - lmtp_user_concurrency_limit>0 setting was logging unnecessary
   anvil errors.
 - lmtp_user_concurrency_limit is now checked before quota check with
   lmtp_rcpt_check_quota=yes to avoid unnecessary quota work.
 - lmtp: %{userdb:*} variables didn't work in mail_log_prefix
 - autoexpunge settings for mailboxes with wildcards didn't work when
   namespace prefix was non-empty.
 - Fixed writing >2GB to iostream-temp files (used by fs-compress,
   fs-metawrap, doveadm-http)
 - director: Ignore duplicates in director_servers setting.
 - director: Many fixes related to connection handshaking, user moving
   and error handling.
 - director: Don't break with shutdown_clients=no
 - zlib, IMAP BINARY: Fixed internal caching when accessing multiple
   newly created mails. They all had UID=0 and the next mail could have
   wrongly used the previously cached mail.
 - doveadm stats reset wasn't reseting all the stats.
 - auth_stats=yes: Don't update num_logins, since it doubles them when
   using with mail stats.
 - quota count: Fixed deadlocks when updating vsize header.
 - dict-quota: Fixed crashes happening due to memory corruption.
 - dict proxy: Fixed various timeout-related bugs.
 - doveadm proxying: Fixed -A and -u wildcard handling.
 - doveadm proxying: Fixed hangs and bugs related to printing.
 - imap: Fixed wrongly triggering assert-crash in
   client_check_command_hangs.
 - imap proxy: Don't send ID command pipelined with nopipelining=yes
 - imap-hibernate: Don't execute quota_over_script or last_login after
   un-hibernation.
 - imap-hibernate: Don't un-hibernate if client sends DONE+IDLE in one
   IP packet.
 - imap-hibernate: Fixed various failures when un-hibernating.
 - fts: fts_autoindex=yes was broken in 2.2.25 unless
   fts_autoindex_exclude settings existed.
 - fts-solr: Fixed searching multiple mailboxes (patch by x16a0)
 - doveadm fetch body.snippet wasn't working in 2.2.25. Also fixed a
   crash with certain emails.
 - pop3-migration + dbox: Various fixes related to POP3 UIDL
   optimization in 2.2.25.
 - pop3-migration: Fixed "truncated email header" workaround.

v2.2.26 had a couple of nasty bugs left in it, so here's a fixup release. The version number is also a little bit weird, but had to be done this way (although 2.2.26.0.1 could have been another possibility).
 - Fixed some compiling issues.
 - auth: Fixed assert-crash when using NTLM or SKEY mechanisms and
   multiple passdbs.
 - auth: Fixed crash when exporting to auth-worker passdb extra fields
   that had empty values.
 - dsync: Fixed assert-crash in dsync_brain_sync_mailbox_deinit

Split off dovecot2-{gssapi,ldap,mysql,pgsql,sqlite} as separate
packages, remove respective options.mk parts.

Changes 2.2.25:
* lmtp: Start tracking lmtp_user_concurrency_limit and reject already
  at RCPT TO stage. This avoids MTA unnecessarily completing DATA only
  to get an error.
* doveadm: Previously only mail settings were read from protocol
  doveadm { .. } section. Now all settings are.

+ quota: Added quota_over_flag_lazy_check setting. It avoids checking
  quota_over_flag always at startup. Instead it's checked only when
  quota is being read for some other purpose.
+ auth: Added a new auth policy service:
  http://wiki2.dovecot.org/Authentication/Policy
+ auth: Added PBKDF2 password scheme
+ auth: Added %{auth_user}, %{auth_username} and %{auth_domain}
+ auth: Added ":remove" suffix to extra field names to remove them.
+ auth: Added "delay_until=<timestamp>[+<max random secs>]" passdb
  extra field. The auth will wait until <timestamp> and optionally some
  randomness and then return success.
+ dict proxy: Added idle_msecs=<n> parameter. Support async operations.
+ Performance improvements for handling large mailboxes.
+ Added lib-dcrypt API for providing cryptographic functions.
+ Added "doveadm mailbox update" command
+ imap commands' output now includes timing spent on the "syncing"
  stage if it's larger than 0.
+ cassandra: Added metrics=<path> to connect setting to output internal
  statistics in JSON format every second to <path>.
+ doveadm mailbox delete: Added -e parameter to delete only empty
  mailboxes. Added --unsafe option to quickly delete a mailbox,
  bypassing lazy_expunge and quota plugins.
+ doveadm user & auth cache flush are now available via doveadm-server.
+ doveadm service stop <services> will stop specified services while
  leaving the rest of Dovecot running.
+ quota optimization: Avoid reading mail sizes for backends which
  don't need them (count, fs, dirsize)
+ Added mailbox { autoexpunge_max_mails=<n> } setting.
+ Added welcome plugin: http://wiki2.dovecot.org/Plugins/Welcome
+ fts: Added fts_autoindex_exclude setting.
- v2.2.24's MIME parser was assert-crashing on mails having truncated
  MIME headers.
- auth: With multiple userdbs the final success/failure result wasn't
  always correct. The last userdb's result was always used.
- doveadm backup was sometimes deleting entire mailboxes unnecessarily.
- doveadm: Command -parameters weren't being sent to doveadm-server.
- If dovecot.index read failed e.g. because mmap() reached VSZ limit,
  an empty index could have been opened instead, corrupting the
  mailbox state.
- imapc: Fixed EXPUNGE handling when imapc_features didn't have modseq.
- lazy-expunge: Fixed a crash when copying failed. Various other fixes.
- fts-lucene: Fixed crash on index rescan.
- auth_stats=yes produced broken output
- dict-ldap: Various fixes
- dict-sql: NULL values crashed. Now they're treated as "not found".

PLIST fix when ldap PKG_OPTIONS is not set, noted by Hauke Fath via
private e-mail.

Update dovecot2 to 2.2.24 (Dovecot 2.2.24).

v2.2.24 2016-04-26  Timo Sirainen <tss@iki.fi>

	* doveconf now warns if it sees a global setting being changed when
	  the same setting was already set inside some filters. (A common
	  mistake has been adding more plugins to a global mail_plugins
	  setting after it was already set inside protocol { .. }, which
	  caused the global setting to be ignored for that protocol.)
	* LMTP proxy: Increased default timeout 30s -> 125s. This makes it
	  less likely to reach the timeout and cause duplicate deliveries.
	* LMTP and indexer now append ":suffix" to session IDs to make it
	  unique for the specific user's delivery. (Fixes duplicate session
	  ID warnings in stats process.)

	+ Added dict-ldap for performing read-only LDAP dict lookups.
	+ lazy-expunge: All mails can be saved to a single specified mailbox.
	+ mailbox { autoexpunge } supports now wildcards in mailbox names.
	+ doveadm HTTP API: Added support for proxy commands
	+ imapc: Reconnect when getting disconnected in non-selected state.
	+ imapc: Added imapc_features=modseq to access MODSEQs/HIGHESTMODSEQ.
	  This is especially useful for incremental dsync.
	+ doveadm auth/user: Auth lookup performs debug logging if
	  -o auth_debug=yes is given to doveadm.
	+ Added passdb/userdb { auth_verbose=yes|no } setting.
	+ Cassandra: Added user, password, num_threads, connect_timeout and
	  request_timeout settings.
	+ doveadm user -e <value>: Print <value> with %variables expanded.
	- Huge header lines could have caused Dovecot to use too much memory
	  (depending on config and used IMAP commands). (Typically this would
	  result in only the single user's process dying with out of memory
	  due to reaching service { vsz_limit } - not a global DoS).
	- dsync: Detect and handle invalid/stale -s state string better.
	- dsync: Fixed crash caused by specific mailbox renames
	- auth: Auth cache is now disabled passwd-file. It was unnecessary and
	  it broke %variables in extra fields.
	- fts-tika: Don't crash if it returns 500 error
	- dict-redis: Fixed timeout handling
	- SEARCH INTHREAD was crashing
	- stats: Only a single fifo_listeners was supported, making it
	  impossible to use both auth_stats=yes and mail stats plugin.
	- SSL errors were logged in separate "Stacked error" log lines
	  instead of as part of the disconnection reason.
	- MIME body parser didn't handle properly when a child MIME part's
	  --boundary had the same prefix as the parent.

PLIST fix

Changes 2.2.23:
This is a bugfix-only release with various important fixes on top of v2.2.22.
 - Various fixes to doveadm. Especially running commands via
   doveadm-server was broken.
 - director: Fixed user weakness getting stuck in some situations
 - director: Fixed a situation where directors keep re-sending
   different states to each others and never becoming synced.
 - director: Fixed assert-crash related to a slow "user killed" reply
 - Fixed assert-crash related to istream-concat, which could have
   been triggered at least by a Sieve script.

Changes 2.2.21:
- doveadm mailbox list (and some others) were broken in v2.2.20
- director: Fixed making backend changes when running with only a
  single director server.
- virtual plugin: Fixed crash when trying to open nonexistent
  autocreated backend mailbox.

Changes 2.2.19:
* pop3_deleted_flag has been broken since v2.2.10. Using it would
  cause buffer overflows, which could be exploitable. However, this
  bug would have become visible quite soon after users had deleted
  some POP3 mails, because the pop3 processes would have started
  crashing all the time even in normal use.
* "doveadm director flush" command has a changed meaning now:
  It safely moves users to their wanted backends, instead of simply
  forgetting the mapping entirely and leaving the existing connections
  untouched. Use -F parameter to get the original unsafe behavior.

+ Added imap-hibernate processes (see imap_hibernate_timeout setting).
  IDLEing IMAP connections can be hibernated, which saves memory.
+ Optimized tracking mailboxes' vsizes (= sum of all messages' sizes).
  If mailbox_list_index=yes, it's also stored in there. This makes it
  very efficient to look up vsizes for all mailboxes.
+ Added a quota "count" backend, which uses the mailbox vsizes to get
  the current quota usage. It requires using the new quota_vsizes=yes
  setting, which tracks the messages' "virtual sizes" rather than
  "physical sizes". Their distiction is minor and mostly irrelevant
  nowadays (if mail sizes should be counted with LF or CRLF newlines).
+ "doveadm director up/down" commands added. The monitoring script
  should be using these commands instead of changing the vhost count.
  This allows admin to manually disable a server by changing the vhost
  count to 0 without the monitoring script changing it back.
+ Added support for HAProxy protocol: http://wiki2.dovecot.org/HAProxy
+ Added push-notification plugin framework, which can be used to
  easily implement push notifications to various backends. Implemented
  "ox" backend for notifying Open-Xchange via HTTP/json.
+ imap_logout_format supports more variables now, e.g. number of
  deleted messages.
+ pop3: Added pop3_delete_type setting (related to pop3_deleted_flag).
+ plugin { fts_enforced=yes } setting now fails body searches unless
  it can be done via the full text search engine.
+ Added %{passdb:*} and %{userdb:*} variables to various places
+ auth: Added ":protected" suffix for passdb and userdb fields. If
  used, the field doesn't overwrite an existing field.
+ IMAP/POP3 proxy: If a backend server dies, avoid client reconnection
  spikes by slowly disconnecting clients over time. This is enabled by
  setting login_proxy_max_disconnect_delay=secs passdb extra field.
+ imap: Added new read-only METADATA entries: /private/specialuse,
  /shared/comment, /shared/admin
+ imap: If client disconnects in the middle of a command, log how long
  the command had been running.
- mdbox: Rebuilding could have caused message's reference count to
  overflow the 16bit number in some situations, causing problems when
  trying to expunge the duplicates.
- Various search fixes (fts, solr, tika, lib-charset, indexer)
- Various virtual plugin fixes
- Various fixes and optimizations to dsync, imapc and pop3-migration
- imap: Various RFC compliancy and crash fixes to NOTIFY

Update dovecot2 package to 2.2.18.

v2.2.18 2015-05-15  Timo Sirainen <tss@iki.fi>

	- director: Login UNIX sockets were normally detected as doveadm or
	  director ring sockets, causing it to break in existing installations.
	- sdbox: When copying a mail in alt storage, place the destination to
	  alt storage as well.

v2.2.17 2015-05-13  Timo Sirainen <tss@iki.fi>

	* Dovecot no longer checks or warns if a mountpoint is removed. This
	  was causing more trouble than it was worth. Make sure that all the
	  mountpoints that Dovecot accesses aren't writable by mail processes
	  when they're unmounted.
	* dict server wasn't properly escaping/unescaping data. Fixing this
	  broke backwards compatibility with data that contains line feeds.
	  This hopefully affects only very few installations. If you're using
	  dict to save multiline data (Sieve scripts to SQL), you may be
	  affected.
	* imap: SPECIAL-USE capability is no longer advertised if there are
	  no special_use flags specified for any mailboxes.

	+ lmtp: Added lmtp_hdr_delivery_address setting to specify whether
	  to include email address in Delivered-To: and Received: headers.
	+ Added initial version of full text search library, which includes
	  language-specific text normalization and filtering. This is still
	  in development, but it's already possible to use for testing with
	  fts-lucene and fts-solr.
	+ lda, lmtp: deliver_log_format can now include %{delivery_time},
	  which expands to how many milliseconds it took to deliver the mail.
	  With LMTP %{session_time} also expands to how many milliseconds the
	  LMTP session took, not including the delivery time.
	+ lmtp proxy: Mail delivery logging includes timing information.
	+ imap: Most IMAP commands now include in the tagged reply how many
	  milliseconds it took to run the command (not counting the time spent
	  on waiting for the IMAP client to read/write data).
	+ director: Implemented director_proxy_maybe passdb extra field to
	  be able to run director and backend in the same Dovecot instance.
	  (LMTP doesn't support mixed proxy/non-proxy destinations currently.)
	+ doveadm: Added -F <file> parameter to read a list of users from the
	  given file and run the command for all the users. This is similar to
	  -A parameter reading the list of users from userdb lookup.
	+ Implemented initial Cassandra CQL support as lib-sql backend. It's
	  only usable as dict backend currently.
	+ Added quota-clone plugin to copy current quota usage to a dict.
	- auth: If auth_master_user_separator was set, auth process could be
	  crashed by trying to log in with empty master username.
	- imap-login, pop3-login: Fixed crash on handshake failures with new
	  OpenSSL versions (v1.0.2) when SSLv3 was disabled.
	- auth: If one passdb fails allow_nets check, it shouldn't have failed
	  all the other passdb checks later on.
	- imap: Server METADATA couldn't be accessed
	- imapc: Fixed \Muted label handling in gmail-migration.
	- imapc: Various bugfixes and improvements.
	- Trash plugin fixes by Alexei Gradinari
	- mbox: Fixed crash/corruption in some situations

Changes 2.2.16:
* dbox: Resyncing (e.g. doveadm force-resync) no longer deletes
  dovecot.index.cache file. The cache file was rarely the problem
  so this just caused unnecessary slowness.
* Mailbox name limits changed during mailbox creation: Each part of
  a hierarchical name (e.g. "x" or "y" in "x/y") can now be up to 255
  chars long (instead of 200). This also reduces the max number of
  hierarchical levels to 16 (instead of 20) to keep the maximum name
  length 4096 (a common PATH_MAX limit). The 255 char limit is
  hopefully large enough for migrations from all existing systems.
  It's also the limit on many filesystems.

+ director: Added director_consistent_hashing setting to enable
  consistent hashing (instead of the mostly-random MD5 hashing).
  This causes fewer user moves between backends when backend counts
  are changed, which may improve performance (mainly due to caching).
+ director: Added support for "tags", which allows one director ring
  to serve multiple backend clusters with different sets of users.
+ LMTP server: Added lmtp_user_concurrency_limit setting to limit how
  many LMTP deliveries can be done concurrently for a single user.
+ LMTP server: Added support for STARTTLS command.
+ If logging data is generated faster than it can be written, log a
  warning about it and show information about it in log process's
  process title in ps output. Also don't allow a single service to
  flood too long at the cost of delaying other services' logging.
+ stats: Added support for getting global statistics.
+ stats: Use the same session IDs as the rest of Dovecot.
+ stats: Plugins can now create their own statistics fields
+ doveadm server: Non-mail related commands can now also be used
  via doveadm server (TCP socket).
+ doveadm proxying: passdb lookup can now override doveadm_port and
  change the username.
+ doveadm: Search query supports now "oldestonly" parameter to stop
  immediately on the first non-match. This can be used to optimize:
  doveadm expunge mailbox Trash savedbefore 30d oldestonly
+ doveadm: Added "save" command to directly save mails to specified
  mailbox (bypassing Sieve).
+ doveadm fetch: Added body.snippet field, which returns the first
  100 chars of a message without whitespace or HTML tags. The result
  is stored into dovecot.index.cache, so it can be fetched efficiently.
+ dsync: Added -t <timestamp> parameter to sync only mails newer than
  the given received-timestamp.
+ dsync: Added -F [-]<flag> parameter to sync only mails with[out] the
  given flag/keyword.
+ dsync: Added -a <mailbox> parameter to specify the virtual mailbox
  containing user's all mails. If this mailbox is already found to
  contain the wanted mail (by its GUID), the message is copied from
  there instead of being re-saved. (This isn't efficient enough yet
  for incremental replication.)
+ dsync: -m parameter can now specify \Special-use names for mailboxes.
+ imapc: Added imapc_features=gmail-migration to help migrations from
  GMail. See http://wiki2.dovecot.org/Migration/Gmail
+ imapc: Added imapc_features=search to support IMAP SEARCH command.
  (Currently requires ESEARCH support from remote server.)
+ expire plugin: Added expire_cache=yes setting to cache most of the
  database lookups in dovecot index files.
+ quota: If overquota-flag in userdb doesn't match the current quota
  usage, execute a configured script.
+ redis dict: Added support for expiring keys (:expire_secs=n) and
  specifying the database number (:db=n)
- auth: Don't crash if master user login is attempted without
  any configured master=yes passdbs
- Parsing UTF-8 text for mails could have caused broken results
  sometimes if buffering was split in the middle of a UTF-8 character.
  This affected at least searching messages.
- String sanitization for some logged output wasn't done properly:
  UTF-8 text could have been truncated wrongly or the truncation may
  not have happened at all.
- fts-lucene: Lookups from virtual mailbox consisting of over 32
  physical mailboxes could have caused crashes.

Add tcpwrapper PKG_OPTIONS and enable it default.

Bump PKGREVISION.

Update dovecot2 to 2.2.15.

Some small fixes and changes to v2.2.14. This release is mainly in the hope
that it could still make it into the next Debian stable instead of v2.2.14 -
mainly because of a couple of new assert crashes that started happening in
v2.2.14 and should be fixed now.

	* Plugins can now print a banner comment in doveconf output
	  (typically the plugin version)
	* Replication plugin now triggers low (instead of high) priority for
	  mail copying operations.
	* IMAP/POP3/ManageSieve proxy: If destination server can't be
	  connected to, retry connecting once per second up to the value of
	  proxy_timeout. This allows quick restarts/upgrades on the backend
	  server without returning login failures.
	* Internal passdb lookups (e.g. done by lmtp/doveadm proxy) wasn't
	  returning failure in some situations where it should have (e.g.
	  allow_nets mismatch)
	* LMTP uses mail_log_prefix now for logging mail deliveries instead of
	  a hardcoded prefix. The non-delivery log prefix is still hardcoded
	  though.

	+ passdb allow_nets=local matches lookups that don't contain an IP
	  address (internally done by Dovecot services)
	+ Various debug logging and error logging improvements
	- Various race condition fixes to LAYOUT=index
	- v2.2.14 virtual plugin crashed in some situations

Changes 2.2.14:
* lmtp: Delivered-To: header no longer contains <> around the email
  address. Other MDAs don't have it either.
* "Out of disk space" errors are now treated as temporary errors
  (not the same as "Out of disk quota").
* replication plugin: Use replication only for users who have a
  non-empty mail_replica setting.

+ lmtp proxy: Log a line about each mail delivery.
+ Added login_source_ips setting. This can be used to set the source IP
  address round-robin from a pool of IPs (in case you run out of TCP
  ports).
+ Rawlog settings can use tcp:<host>:<port> as the path.
+ virtual plugin: Don't keep more than virtual_max_open_mailboxes
  (default 64) number of backend mailboxes open.
+ SSL/TLS compression can be disabled with ssl_options=no_compression
+ acl: Global ACL file now supports "quotes" around patterns.
+ Added last-login plugin to set user's last-login timestamp on login.
+ LDAP auth: Allow passdb credentials lookup also with auth_bind=yes
- IMAP: MODSEQ was sent in FETCH reply even if CONDSTORE/QRESYNC wasn't
  enabled. This broke at least old Outlooks.
- passdb static treated missing password field the same as an empty
  password field.
- mdbox: Fixed potential infinite looping when scanning a broken
  mdbox file.
- imap-login, pop3-login: Fixed potential crashes when client
  disconnected unexpectedly.
- imap proxy: The connection was hanging in some usage patterns. This
  mainly affected older Outlooks.
- lmtp proxy: The proxy sometimes delivered empty mails in error
  situations or potentially delivered truncated mails.
- fts-lucene: If whitespace_chars was set, we may have ended up
  indexing some garbage words, growing the index size unnecessarily.
- -c and -i parameters for dovecot/doveadm commands were ignored if
  the config socket was readable.
- quota: Quota recalculation didn't include INBOX in some setups.
- Mail headers were sometimes added to dovecot.index.cache in wrong
  order. The main problem this caused was with dsync+imapc incremental
  syncing when the second sync thought the local mailbox had changed.
- doveadm backup didn't notice if emails were missing from the middle
  of the destination mailbox. Now it deletes and resyncs the mailbox.

   Log Message:
   Changes 2.2.13:
   * Fixed a DoS attack against imap/pop3-login processes. If SSL/TLS
     handshake was started but wasn't finished, the login process
     attempted to eventually forcibly disconnect the client, but failed
     to do it correctly. This could have left the connections hanging
     arond for a long time. (Affected Dovecot v1.1+)

   + mdbox: Added mdbox_purge_preserve_alt setting to keep the file
     within alt storage during purge. (Should become enforced in v2.3.0?)
   + fts: Added support for parsing attachments via Apache Tika. Enable
     with: plugin { fts_tika = http://tikahost:9998/tika/ }
   + virtual plugin: Delay opening backend mailboxes until it's necessary.
     This requires mailbox_list_index=yes to work. (Currently IMAP IDLE
     command still causes all backend mailboxes to be opened.)
   + mail_never_cache_fields=* means now to disable all caching. This may
     be a useful optimization as doveadm/dsync parameter for some admin
     tasks which shouldn't really update the cache file.
   + IMAP: Return SPECIAL-USE flags always for LSUB command.
   - pop3 server was still crashing in v2.2.12 with some settings
   - maildir: Various fixes and improvements to handling compressed mails,
     especially when they have broken/missing S=sizes in filenames.
   - fts-lucene, fts-solr: Fixed crash on search when the index contained
     duplicate entries.
   - Many fixes and performance improvements to dsync and replication
   - director was somewhat broken when there were exactly two directors
     in the ring. It caused errors about "weak users" getting stuck.
   - mail_attachment_dir: Attachments with the last base64-encoded line
     longer than the rest wasn't handled correctly.
   - IMAP: SEARCH/SORT PARTIAL was handled completely wrong in v2.2.11+
   - acl: Global ACL file handling was broken when multiple entries
     matched the mailbox name. (Only the first entry was used.)

Remove example rc.d scripts from PLISTs.

These are now handled dynamically if INIT_SYSTEM is set to "rc.d", or
ignored otherwise.

Changes 2.2.11:
+ acl plugin: Added an alternative global ACL file that can contain
  mailbox patterns. See http://wiki2.dovecot.org/ACL for details.
+ imap proxy: Added proxy_nopipelining passdb setting to work around
  other IMAP servers' bugs (MS Exchange 2013 especially).
+ Added %{auth_user}, %{auth_username} and %{auth_domain} variables.
  See http://wiki2.dovecot.org/Variables for details.
+ Added support for LZ4 compression.
+ stats: Track also wall clock time for commands.
+ pop3_migration plugin improvements to try harder to match the UIDLs
  correctly.
- imap: SEARCH/SORT PARTIAL reponses may have been too large.
- doveadm backup: Fixed assert-crash when syncing mailbox deletion.

Changes 2.2.10:
+ auth: passdb/userdb dict rewrite to support much more complex
  setups. See doc/example-config/dovecot-dict-auth.conf.ext.
  The old settings will continue to work.
+ auth: Added userdb result_success/failure/tempfail and skip
  settings, similar to passdb's. See
  http://wiki2.dovecot.org/UserDatabase
+ imap: Implemented SETQUOTA command for admin user when quota_set is
  configured. See http://master.wiki2.dovecot.org/Quota/Configuration
+ quota: Support "*" and "?" wildcards in mailbox names in quota_rules
+ mysql: Added ssl_verify_server_cert=no|yes parameter. This currently
  defaults to "no" to make sure nothing breaks, but likely will become
  "yes" in Dovecot v2.3.
+ ldap: Added blocking=yes setting to use auth worker processes for
  ldap lookups. This is a workaround for now to be able to use multiple
  simultaneous LDAP connections.
+ pop3c+dsync performance improvements
- quota-status: quota_grace was ignored
- ldap: Fixed memory leak with auth_bind=yes and without
  auth_bind_userdn.
- imap: Don't send HIGHESTMODSEQ anymore on SELECT/EXAMINE when
  CONDSTORE/QRESYNC has never before been enabled for the mailbox.
- imap: Fixes to handling mailboxes without permanent modseqs.
  (When [NOMODSEQ] is returned by SELECT, mainly with in-memory
  indexes.)
- imap: Various fixes to METADATA support.
- stats plugin: Processes that only temporarily dropped privileges
  (e.g. indexer-worker) may have been logging errors about not being
  able to open /proc/self/io.

   Log Message:
   Changes 2.2.7:
   * Some usage of passdb checkpassword could have been exploitable by
     local users. You may need to modify your setup to keep it working.
     See http://wiki2.dovecot.org/AuthDatabase/CheckPassword#Security
   + auth: Added ability to truncate values logged by
     auth_verbose_passwords (see 10-logging.conf comment)
   + mdbox: Added "mdbox_deleted" storage, which can be used to access
     messages with refcount=0. For example: doveadm import
     mdbox_deleted:~/mdbox "" mailbox inbox subject oops
   + ssl-params: Added ssl_dh_parameters_length setting.
   - master process was doing a hostname.domain lookup for each created
     process, which may have caused a lot of unnecessary DNS lookups.
   - dsync: Syncing over 100 messages at once caused problems in some
     situations, causing messages to get new UIDs.
   - fts-solr: Different Solr hosts for different users didn't work.

Changes 2.2.9:
+ Full text search indexing can now be done automatically after
  saving/copying mails by setting plugin { fts_autoindex=yes }
+ replicator: Added replication_dsync_parameters setting to pass
  "doveadm sync" parameters (for controlling what to replicate).
+ Added mail-filter plugin
+ Added liblzma/xz support (zlib_save=xz)
- v2.2.8's improved cache file handling exposed several old bugs
  related to fetching mail headers.
- v2.2.7's iostream handling changes were causing some connections
  to be disconnected before flushing their output (e.g. POP3 logout
  message wasn't being sent)

Changes 2.2.8:
+ Mail cache lookups work for the mail being saved. This improves
  performance by avoiding the need to parse the mail multiple times
  when using some plugins (e.g. mail_log).
+ Mail cache works for recently cached data also with in-memory
  indexes.
+ imapc: Many performance improvements, especially when working with
  dsync. Also added imapc_feature=fetch-headers which allows using
  FETCH BODY.PEEK[HEADER.FIELDS (..)] to avoid reading the entire
  header.
+ mail_location = ..:FULLDIRNAME=dbox-Mails is the same as
  :DIRNAME=dbox-Mails, but it will also be used for
  :INDEX and :CONTROL directories. (It should have worked this way
  from the beginning, but can't be changed anymore without breaking
  existing installations).
- Fixed infinite loop in message parsing if message ends with
  "--boundary" and CR (without LF). Messages saved via SMTP/LMTP can't
  trigger this, because messages must end with an "LF.". A user could
  trigger this for him/herself though.
- lmtp: Client was sometimes disconnected before all the output was
  sent to it.
- imap_zlib plugin caused crashes during client disconnection in
  v2.2.7
- replicator: Database wasn't being exported to disk every 15 minutes
  as it should have. Instead it was being imported, causing "doveadm
  replicator remove" commands to not work very well.

Changes 2.2.7:
* Some usage of passdb checkpassword could have been exploitable by
  local users. You may need to modify your setup to keep it working.
  See http://wiki2.dovecot.org/AuthDatabase/CheckPassword#Security

+ acl: If plugin { acl_defaults_from_inbox = yes } is set, get the
  default ACLs for private and shared namespaces from the user's INBOX.
  (This probably will become default in v2.3.)
+ pop3: Added pop3_deleted_flag setting to switch POP3 deletions to
  only hide the messages from POP3, but still be visible via IMAP.
- ACL plugin: Mailbox creation wasn't actually checking any ACLs
  and always succeeded (due to some v2.2 API changes). The created
  mailbox couldn't have been accessed though, so this couldn't have
  caused any data leak.
- IMAP: Various URLAUTH fixes.
- IMAP: Fixed a hang with invalid APPEND parameters.
- IMAP LIST-EXTENDED: INBOX was never listed with \Subscribed flag.
- mailbox_list_index=yes still caused crashes.
- maildir: Fixed a crash after dovecot-keywords file was re-read.
- maildir: If files had reappeared unexpectedly to a Maildir, they
  were ignored until index files were deleted.
- Maildir: Fixed handling over 26 keywords in a mailbox.
- Maildir++: Fixed mail_shared_explicit_inbox=no
- namespace { prefix="" list=no } was listing mailboxes.
- imap/pop3-login proxying: Fixed a crash if TCP connection succeeded,
  but the remote login timed out.
- Case-insensitive search/sort didn't work correctly for all unicode
  characters, as specified by i;unicode-casemap comparator. If full
  text search indexes were used, they need to be rebuilt for old mails
  to be handled correctly. (This bug has existed always in Dovecot.)

Add share/doc/dovecot/wiki/MailboxSettings.txt to PLIST.

Bump PKGREVISION.

Upgrade to dovecot-2.2.1. Changes since 2.2.0, from NEWS file:

v2.2.1 2013-04-19  Timo Sirainen <tss@iki.fi>
        - mailbox_list_index=yes was broken.
        - LAYOUT=index didn't list subscriptions.
        - auth: Multiple master passdbs didn't work.
        - Message parsing (e.g. during search) crashed when multipart message
          didn't actually contain any parts.

Upgrate to doevecot 2.2.0.

Changes since 2.1.13, from the NEWS file

v2.2.0 2013-04-11  Timo Sirainen <tss@iki.fi>

	* When creating home directories, the permissions are copied from the
	  parent directory if it has setgid-bit set. For full details, see
	  http://wiki2.dovecot.org/SharedMailboxes/Permissions
	* "doveadm auth" command was renamed to "doveadm auth test"
	* IMAP: ID command now advertises server name as Dovecot by default.
	  It was already trivial to guess this from command replies.
	* dovecot.index.cache files can be safely accessed only by v2.1.11+.
	  Older versions may think they're corrupted and delete them.
	* LDA/LMTP: If saving a mail brings user from under quota to over
	  quota, allow it based on quota_grace setting (default: 10%
	  above quota limit).
	* pop3_lock_session=yes now uses a POP3-only dovecot-pop3-session.lock
	  file instead of actually locking the mailbox (and causing
	  IMAP/LDA/LMTP to wait for the POP3 session to close).
	* mail_shared_explicit_inbox setting's default switched to "no".
	* ssl_client_ca_dir setting replaced imapc_ssl_ca_dir and
	  pop3c_ssl_ca_dir settings.

	+ Implemented IMAP MOVE and BINARY extensions
	+ Implemented IMAP CATENATE, URLAUTH and URLAUTH=BINARY extensions
	  (by Stephan Bosch).
	+ Implemented IMAP NOTIFY extension. Requires mailbox_list_index=yes
	  to be enabled.
	+ Redesigned and rewritten dsync. The new design makes the syncing
	  faster, more reliable and more featureful. The new dsync protocol
	  isn't backwards compatible with old dsync versions (but is designed
	  to be forwards compatible with future versions).
	+ All mailbox formats now support per-user message flags for shared
	  mailboxes by using a private index. It can be enabled by adding
	  :INDEXPVT=<path> to mail location. This should be used instead of
	  :INDEX also for Maildir/mbox to improve performance.
	+ Improved mailbox list indexes. They should be usable now, although
	  still disabled by default.
	+ Added LAYOUT=index. The mailbox directories are created using their
	  GUIDs in the filesystem, while the actual GUID <-> name mapping
	  exists only in the index.
	+ LMTP proxy: Implemented XCLIENT extension for passing remote IP
	  address through proxy.

v2.2.rc7 2013-04-10  Timo Sirainen <tss@iki.fi>

	* checkpasword: AUTH_PASSWORD environment is no longer set.
	* Running dsync no longer triggers quota warnings.

	+ dsync: Commit large transactions every 100 new messages, so if a
	  large sync crashes it doesn't have to be restarted from the
	  beginning.
	- replicator: doveadm commands and user list export may have skipped
	  some users.
	- Various fixes to mailbox_list_index=yes

v2.2.rc6 2013-04-08  Timo Sirainen <tss@iki.fi>

	* replicator: Don't create replicator-doveadm socket by default.
	  This way doveadm replicator commands don't accidentally start an
	  unconfigured replicator server.
	+ replicator: Have remote dsync notify the remote replicator that
	  a user was just synced. This way the replicators are kept roughly
	  in sync.
	+ Added ssl_client_ca_file to specify the CA certs as a file. This is
	  needed (instead of ssl_client_ca_dir) in RedHat-based systems.
	+ Added "doveadm fs" commands, mainly to debug lib-fs backends.
	- Mailbox list indexes weren't using proper file permissions based
	  on the root directory.

v2.2.rc5 2013-04-05  Timo Sirainen <tss@iki.fi>

	- A few small random fixes

v2.2.rc4 2013-04-05  Timo Sirainen <tss@iki.fi>

	+ Added "doveadm replicator" commands
	- Larger changes to lib-http and lib-ssl-iostream error handling.
	  The API caller can now get the exact error message as a string.
	- Various bugfixes to LDAP changes in rc3

v2.2.rc3 2013-03-20  Timo Sirainen <tss@iki.fi>

	+ dsync: Support syncing ACLs (and Sieve scripts with Pigeonhole)
	+ ldap: Support subqueries and value pointers, see
	  http://wiki2.dovecot.org/AuthDatabase/LDAP/Userdb
	+ postmaster_address setting: Expand %d to recipient's domain
	- Fixed a crash when decoding quoted-printable content.
	- dsync: Various bugfixes

v2.2.rc2 2013-02-15  Timo Sirainen <tss@iki.fi>

	- rc1 wasn't actually usable in most configurations.

v2.2.rc1 2013-02-15  Timo Sirainen <tss@iki.fi>

	* See v2.2.0 notes

Changes 2.1.15:
v2.1.14's dovecot.index.cache fixes caused Dovecot to use more disk I/O
and memory than was necessary.

Update to 2.1.13 and add support for NetBSD 6.0 libquota

Changes since 2.1.12:
        - Some fixes to cache file changes in v2.1.11.
        - fts-solr: Overlong UTF8 sequences in mails were rejected by Solr and
          caused the mails to not be indexed.
        - virtual storage: Sorting mailbox by from/to/cc/bcc didn't work.

Update to Dovecot 2.1.9

* mail-log plugin: Log mailbox names with UTF-8 everywhere (instead of mUTF-7
  in some places and UTF-8 in other places)
* director: Changed director_username_hash setting's default from %u to %Lu (=
  lowercase usernames). This doesn't break any existing installations, but
  might fix some of them.

+ doveadm: Added "auth cache flush [<username>]" command.
+ Implemented dict passdb/userdb
+ Implemented Redis and memcached dict backends, which can be used as auth
  backends. Redis can also be used as dict-quota backend.
+ Added plugin { quota_ignore_save_errors=yes } setting to allow saving a mail
  when quota lookup fails with temporary failure.
- Full text search indexing might have failed for some messages, always causing
  indexer-worker process to run out of memory.
- fts-lucene: Fixed handling SEARCH HEADER FROM/TO/SUBJECT/CC/BCC when the
  header wasn't lowercased.
- fts-squat: Fixed crash when searching a virtual mailbox.
- pop3: Fixed assert crash when doing UIDL on empty mailbox on some setups.
- auth: GSSAPI RFC compliancy and error handling fixes.
- Various fixes related to handling shared namespaces

update to 2.1.8
changes:
-pop3c: Added pop3c_master_user setting
-bugfix: Mailbox names were accidentally sent as UTF-8 instead of mUTF-7
-more bugfixes

approved by The Maintainer

Update to Dovecot 2.1.5

* IMAP: When neither the session nor the mailbox has modseq tracking enabled,
  return the mailbox as having NOMODSEQ in SELECT/EXAMINE reply. Old versions
  in this situation always simply returned HIGHESTMODSEQ as 1, which could have
  broken some clients.

+ dict file: Added optional fcntl/flock locking (default is dotlock)
+ fts-solr: doveadm fts rescan now resets indexes, which allows reindexing
  mails. (This isn't a full rescan implementation like fts-lucene has.)
+ doveadm expunge: Added -d parameter to delete mailbox if it's empty after
  expunging.
- IMAP: Several fixes related to mailbox listing in some configs
- director: A lot of fixes and performance improvements
- v2.1.4 didn't work without a mail home directory set
- mbox: Deleting a mailbox didn't delete its index files.
- pop3c: TOP command was sent incorrectly
- trash plugin didn't work properly
- LMTP: Don't add a duplicate Return-Path: header when proxying.
- listescape: Don't unescape namespace prefixes.

Update to Dovecot 2.1.4.

+ Added mail_temp_scan_interval setting and changed its default value
  from 8 hours to 1 week.
+ Added pop3-migration plugin for easily doing a transparent IMAP+POP3
  migration to Dovecot: http://wiki2.dovecot.org/Migration/Dsync
+ doveadm user: Added -m parameter to show some of the mail settings.
- Proxying SSL connections crashed in v2.1.[23]
- fts-solr: Indexing mail bodies was broken.
- director: Several changes to significantly improve error handling
- doveadm import didn't import messages' flags
- mail_full_filesystem_access=yes was broken
- Make sure IMAP clients can't create directories when accessing
  nonexistent users' mailboxes via shared namespace.
- Dovecot auth clients authenticating via TCP socket could have failed
  with bogus "PID already in use" errors.

Update to Dovecot 2.1.3.  Changelog since 2.1.1:

There are a ton of proxying related improvements in this release. You
should now be able to do pretty much anything you want with Dovecot
proxy/director.

This release also includes the initial version of dsync-based replication.
I'm already successfully using it for @dovecot.fi mails, but it still has
some problems. See http://dovecot.org/list/dovecot/2012-March/064243.html
for some details how to configure it.

+ Initial implementation of dsync-based replication. For now this
  should be used only on non-critical systems.
+ Proxying: POP3 now supports sending remote IP+port from proxy to
  backend server via Dovecot-specific XCLIENT extension.
+ Proxying: proxy_maybe=yes with host=<hostname> (instead of IP)
  works now properly.
+ Proxying: Added auth_proxy_self setting
+ Proxying: Added proxy_always extra field (see wiki docs)
+ Added director_username_hash setting to specify what part of the
  username is hashed. This can be used to implement per-domain
  backends (which allows safely accessing shared mailboxes within
  domain).
+ Added a "session ID" string for imap/pop3 connections, available
  in %{session} variable. The session ID passes through Dovecot
  IMAP/POP3 proxying to backend server. The same session ID is can be
  reused after a long time (currently a bit under 9 years).
+ passdb checkpassword: Support "credentials lookups" (for
  non-plaintext auth and for lmtp_proxy lookups)
+ fts: Added fts_index_timeout setting to abort search if indexing
  hasn't finished by then (default is to wait forever).
- doveadm sync: If mailbox was expunged empty, messages may have
  become back instead of also being expunged in the other side.
- director: If user logged into two directors while near user
  expiration, the directors might have redirected the user to two
  different backends.
- imap_id_* settings were ignored before login.
- Several fixes to mailbox_list_index=yes
- Previous v2.1.x didn't log all messages at shutdown.
- mbox: Fixed accessing Dovecot v1.x mbox index files without errors.

Update to Dovecot 2.1.1.  Major changes since 2.0.x:

* Plugins now use UTF-8 mailbox names rather than mUTF-7: acl, autocreate,
  expire, trash, virtual
* auth_username_format default changed to %Lu. If you really want case
  sensitive usernames, set it back to empty.
* Solr full text search backend changed to use mailbox GUIDs instead of mailbox
  names, requiring reindexing everything. solr_old backend can be used with old
  indexes to avoid reindexing, but it doesn't support some newer features.
* Expire plugin: Only go through users listed by userdb iteration.  Delete dict
  rows for nonexistent users, unless expire_keep_nonexistent_users=yes.
* Temporary authentication failures sent to IMAP/POP3 clients now includes the
  server's hostname and timestamp. This makes it easier to find the error
  message from logs.
* dsync was merged into doveadm. There is still "dsync" symlink pointing to
  "doveadm", which you can use the old way for now.  The preferred ways to run
  dsync are "doveadm sync" (for old "dsync mirror") and "doveadm backup".

+ imapc (= IMAP client) storage allows using a remote IMAP server to be used as
  storage. This allows using Dovecot as a smart (caching) proxy or using dsync to
  do migration from remote IMAP server.
+ Mailbox indexing via queuing indexer service (required for Lucene)
+ Lucene full text search (FTS) backend rewritten with support for different
  languages
+ FTS finally supports "OR" search operation
+ FTS supports indexing attachments via external programs
+ IMAP FUZZY extension, supported by Lucene and Solr FTS backends
+ IMAP SPECIAL-USE extension to describe mailboxes
+ Mailbox list indexes
+ Statistics tracking via stats service. Exported via doveadm stats.
+ Autocreate plugin creates/subscribes mailboxes physically only when the
  mailbox is opened for the first time. Mailbox listing shows the autocreated
  mailboxes even if they don't physically exist.
+ Password and user databases now support default_fields and override_fields
  settings to specify template defaults/overrides.
+ SCRAM-SHA-1 authentication mechanism by Florian Zeitz
+ LDAP: Allow building passdb/userdb extra fields from multiple LDAP attributes
  by using %{ldap:attributeName} variables in the template.
+ Improved multi-instance support: Track automatically which instances are
  started up and manage the list with doveadm instance commands.  All Dovecot
  commands now support -i <instance_name> parameter to select the instance
  (instead of having to use -c <config path>).  See instance_name setting.
+ auth: Implemented support for Postfix's "TCP map" sockets for user existence
  lookups.
- listescape plugin works perfectly now

Changes since 2.1.0:

+ dsync: If message with same GUID is saved multiple times in session, copy it
  instead of re-saving.
- acl plugin + autocreated mailboxes crashed when listing mailboxes
- doveadm force-resync: Don't skip autocreated mailboxes (especially INBOX).
- If process runs out of fds, stop listening for new connections only
  temporarily, not permanently (avoids hangs with process_limit=1 services)
- auth: passdb imap crashed for non-login authentication (e.g. smtp).

Changes 2.0.17:
* Proxying now supports sending SSL client certificate to server with
  ssl_client_cert/key settings.
* doveadm dump: Added support for dumping dbox headers/metadata.
* Fixed memory leaks in login processes with SSL connections
* vpopmail support was broken in v2.0.16

   Log Message:
   Update to Dovecot 2.0.16.

   * VSZ limits weren't being enforced for any processes. On server with
     large mailboxes you may now see errors about it if the limits aren't
     high enough. To fix them, either increase individual service {
     vsz_limit } values or simply increase the default_vsz_limit setting.
   * Proxying: If using ssl=3Dyes or starttls=3Dyes with a hostname (not IP)
     as proxy destination, require that the certificate matches the given
     hostname.
   * LMTP: Changed default client_limit to 1. This should improve LMTP
     throughput with default settings.
   * dsync: Quota is no longer enforced (i.e. dsync can't fail because
     user is over quota).

   + Added "auto" mail storage driver, which can be used to autodetect
     mailbox location and format. This behavior is already the default
     for empty mail_location setting, so this change is mainly useful for
     shared namespace's location setting.
   + checkpassword: Export all auth %variables to AUTH_* environment.

- v2.0.10: dsyncing to remote often hanged (timed out in 15 mins)

Chamges 2.0.10:
* LMTP: For user+detail at domain deliveries, the +detail is again written
  to Delivered-To: header.
* Skip auth penalty checks from IPs in login_trusted_networks.
+ Added import_environment setting.
+ Added submission_host setting to send mails via SMTP instead of
  via sendmail binary.
+ Added doveadm acl get/set/delete commands for ACL manipulation,
  similar to how IMAP ACL extension works.
+ Added doveadm acl debug command to help debug and fix problems
  with why shared mailboxes aren't working as expected.
- IMAP: Fixed hangs with COMPRESS extension
- IMAP: Fixed a hang when trying to COPY to a nonexistent mailbox.
- IMAP: Fixed hang/crash with SEARCHRES + pipelining $.
- IMAP: Fixed assert-crash if IDLE+DONE is sent in same TCP packet.
- LMTP: Fixed sending multiple messages in a session.
- doveadm: Fixed giving parameters to mail commands.
- doveadm import: Settings weren't correctly used for the
  import storage.
- dsync: Fixed somewhat random failures with saving messages to
  remote dsync.
- v2.0.9: Config reload didn't notify running processes with
  shutdown_clients=no, so they could have kept serving new clients
  with old settings.

Changes 2.0.9:
* Linux: Fixed a high system CPU usage / high context switch count
  performance problem
* Maildir: Avoid unnecessarily reading dovecot-uidlist while opening
  mailbox.
* Maildir: Fixed renaming child mailboxes when namespace had a prefix.
* mdbox: Don't leave partially written messages to mdbox files when
  aborting saving.
* Fixed master user logins when using userdb prefetch
* lda: Fixed a crash when trying to send "out of quota" reply
* lmtp: If delivering duplicate messages to same user's INBOX,
  create different GUIDs for them. This helps to avoid duplicate
  POP3 UIDLs when pop3_uidl_format=%g.
* virtual storage: Fixed saving multiple mails in a transaction
  (e.g. copy multiple messages).
* dsync: Saved messages' save-date was set to 1970-01-01.

Update to Dovecot 2.0.8.

* Services' default vsz_limits weren't being enforced correctly in
  earlier v2.0 releases. Now that they are enforced, you might notice
  that the default limits are too low and you need to increase them.
  This problem will show up in logs as "out of memory" errors.
  See default_vsz_limit and service { vsz_limit } settings.
* LMTP: In earlier versions if mail was delivered to user+detail@domain
  address, LMTP server always attempted to deliver the mail to mailbox
  named "detail". This was rather unintentional and shouldn't have been
  the default. lmtp_save_to_detail_mailbox=yes setting now preserves
  this behavior (default is no).

+ Added systemd support (configure --with-systemdsystemunitdir).
  Based on patch by Christophe Fergeau.
+ Replaced broken mbox-snarf plugin with a new more generic snarf
  plugin.
- dbox: Fixes to handling external mail attachments
- verbose_proctitle=yes didn't work for all processes in v2.0.7
- imap, pop3: When service { client_count } was larger than 1, the
  log messages didn't use the correct prefix. Last logged in user's
  prefix was always used, regardless of what user's session actually
  logged it. Now the proper log prefix is always used.
- MySQL: Only the first specified host was ever used

Update to Dovecot 2.0.7.

* master: default_process_limit wasn't actually used anywhere,
  rather the default was unlimited. Now that it is enforced, you might
  notice that the default limit is too low and you need to increase it.
  Dovecot logs a warning when this happens.
* mail-log plugin: Log mailbox name as virtual name rather than
  physical name (e.g. namespace prefix is included in the name)

+ doveadm dump: Added imapzlib type to uncompress IMAP's
  COMPRESS DEFLATE I/O traffic (e.g. from rawlog).
- IMAP: Fixed LIST-STATUS when listing subscriptions with
  subscriptions=no namespaces.
- IMAP: Fixed SELECT QRESYNC not to crash on mailbox close if a lot of
  changes were being sent.
- quota: Don't count virtual mailboxes in quota
- doveadm expunge didn't always actually do the physical expunging
- Fixed some index reading optimizations introduced by v2.0.5.
- LMTP proxying fixes

Dovecot is an open source IMAP and POP3 server for Linux/UNIX-like systems,
written with security primarily in mind. Dovecot is an excellent choice for both
small and large installations. It's fast, simple to set up, requires no special
administration and it uses very little memory.
