pkglint -r --network --only "migrate"

As a side-effect of migrating the homepages, pkglint also fixed a few
indentations in unrelated lines. These and the new homepages have been
checked manually.

Update to 5.0.1. From the changelog:

Fixed a typo in the README file for the OpenSSL "dhparam" command.  Thanks to
  Eric Shubert for reporting this one.
Removed unused variables from the dns* commands in the utils folder to fix
  compiler warnings.
Fixed a bug in read_file() that returned uninitialized pointers if a file
  contained blank lines or comments at the top, causing segfaults when they
  were free()d.  Thanks to Jeffrey Gordon and Quinn Comendant for reporting
  this one.
Changed the directory naming scheme in the "generator" program to include the
  flowchart step numbers in the name.  The old pattern was just too hard to
  follow visually and far too difficult to search for a specific test.
Added more steps to the recipient validation flowchart and spamdyke-qrv's
  recipient validation filter to correctly handle addresses that are forwarded
  to an external address.  Thanks to Stephen Marley for reporting this one.
Changed search_file() in spamdyke-qrv to return a "not found" result when the
  file does not exist, instead of an error.
Added a delay loop to exec_command_argv() in spamdyke and spamdyke-qrv to work
  around a race condition -- sometimes the child process will close its pipes
  in preparation for exiting and the parent's waitpid() will fire before the
  child has fully exited. This leads to erroneous returns showing the child
  has not exited when it really only needed another timeslice or two.  This is
  fixed by looping with nanosleep() to wait a few tenths of a second after
  seeing this return code.
Added a way to stop a test script run by creating a file named "stop".  This
  allows it to be stopped without killing the process and potentially leaving
  the test platform in a partially (mis)configured state.
Fixed the accessor function for the header-blacklist-entry and
  header-blacklist-file options to find their data in the filter_settings
  object instead of the option_set object.  This is because the data is moved
  from the option_set immediately after it is set so the blacklist effect is
  cumulative when set from configuration directories.  Reading from the wrong
  location meant the config-test feature was never testing those options at
  all.  Thanks to Stefan for reporting this one.
Fixed a pair of bugs in process_config_file(): one that would add empty values
  to the end of a list of blacklist/whitelist files if a directive was
  followed by a blank line and a commented-out directive (causing errors when
  the values are used), the other that would throw errors if a line in a
  configuration file contained only one space.  Thanks to Les Fenison for
  reporting these.
Fixed a bug in middleman() that would return an improper greeting when
  injecting both AUTH and STARTTLS banners into the EHLO response.  Clients
  seeing this improper greeting would hang forever and eventually timeout.
  Thanks to Elliot Denk for reporting this one and sending a patch!
Fixed a major thinko in smtp_filter that was carrying over the rejection data
  between recipients, even if a recipient had a configuration directory file
  that altered the overall configuration.  This was leading to some
  recipients being incorrectly rejected under very specific (and likely very
  rare) conditions, which just happened to be met on my own server.
Fixed a bug in copy_base_options that was not copying the "reason" data from
  the last rejection.
Fixed an infinite loop in dnsdummy when priorities over 0 are used.
Fixed a typo in dnsdummy that was truncating data when the verbose flags were
  used (weird, yes).
Changed dnsdummy to fork a child process to return each query.  This was the
  easiest solution to implement to allow new queries to be processed while
  waiting n seconds to send answers to previous queries.  This is a fragile
  and wasteful solution -- if dnsdummy were intended for production use, a
  queue would be a much better solution.
Changed all of the "verbose"-level error messages to include the name of the
  function, file and line that generated it.  Every other message prefixed
  with "ERROR" already did this, so this makes things more consistent.
Renamed all of the "FILTER" messages and added a new logging macro to print
  them named SPAMDYKE_LOG_FILTER().  This way they can continue to be output
  without function, file and line information.
Renamed the SPAMDYKE_LOG_CONFIG_TEST() macro to
  instead of having a special LOG_LEVEL_CONFIG_TEST setting.  This way the
  config-test messages can be changed to emit file, function and lines if
  needed (or not).
Changed dnsdummy to encode multiple answers in the same response, if its
  config file contains multiple matches for the same query.
Fixed a bug in dnsdummy that was adding extra bytes to the end of each
  answer.  This turned out to be covering a matching (compensating) bug in
  spamdyke's DNS parsing code.  I really hate it when that happens!
Fixed a serious bug in nihdns_expand() that was causing spamdyke to
  incorrectly parse DNS responses with multiple answers; it would use the
  first answer, then skip the wrong number of bytes, causing it to conclude
  any subsequent answers were corrupted.
Changed nihdns_expand() to return separate values for the number of bytes in
  the decoded string and the number of bytes the string occupies in the DNS
  packet.  Due to packet compression, the numbers can be very different.
Changed generator to add records to the named configuration so domains will
  resolve correctly during testing.  Since using port numbers in resolv.conf
  is not allowed, there is no easy way to use dnsdummy for these tests.
Discovered qmail-send does not check the percenthack or virtualdomains files
  when resolving forward addresses, only locals and assign.  Updated
  spamdyke-qrv to behave the same way.
Refined the success/failure detection in generator after learning more about
  qmail's behavior.  If only it had some kind of accurate documentation...
Extended the tests created by generator to also test conditions where
  spamdyke-qrv calls vpopmail to look up addresses.  This increased the
  number of spamdyke-qrv tests more than tenfold!
Added a "diagnostic output" flag to spamdyke-qrv to print the decision path
  it used to evaluate the address.  Also added a test to the test generator
  to compare the diagnostic output with the expected decision path, to
  catch tests that may be producing the desired effect for the wrong reason.
Fixed a bug in set_config_value() to make it possible to set
  CONFIG_TYPE_NAME_MULTIPLE options to "none" or unset specific values.
  Thanks to Konstantin for reporting this one.
Added flags to smtpdummy to advertise STARTTLS support in response to EHLO.
  It doesn't actually do TLS, it just advertises it.
Fixed smtp_filter() to block a client's STARTTLS command if tls-level is
  "none".  Thanks to Les Fenison for reporting this one.
Added a flag to the configure script for both spamdyke and spamdyke-qrv to
  compile with the address sanitizer library to catch memory access errors.
  Adjusted the version string to show when the sanitizer is in use.
Changed the test scripts to always compile spamdyke with the address
  sanitizer (if available) when testing.  The tests run a lot slower, but
  the sanitizer is too awesome to not use.
Fixed a buffer underrun in examine_entry that was causing segfaults when
  searching files where wildcards are allowed at the beginning of the lines.
  Thanks to Dirk Kannapinn for reporting this one.
Discovered a horrible problem with snprintf()'s %n format -- it returns the
  number of bytes it _would_have_ written *if* there were infinite space, not
  the number of bytes *actually* written as the man page states.  So using %n
  at the end of the format string as a substitute for immediately calling
  strlen() is not safe.  Good thing I don't ever do that, right? ...wait,
  I use that feature EVERYWHERE! (grrrrr)  Thanks to the Google Address
  Sanitizer team for finding this one.  Whoever implemented the %n feature
  in glibc can report to me any time for a free punch in the throat.
  I want my weekend back.
Reverted the (apparently) useless change from 4.3.0 to use %n in snprintf()
  instead of the return value and replaced snprintf() with a macro named
  SNPRINTF() that explicitly compares the return value with the size of the
  buffer and returns the number of bytes ACTUALLY written.
Fixed a harmless buffer overrun in sub_examine_tcprules_entry() that could
  have overwritten one byte of another variable on the stack with a null
  byte.  Since the address was valid and that other variable is set just
  after the overwrite anyway, it wasn't actually a problem.  But fixing it
  makes the address sanitizer happy, so it's fixed.
Fixed a pair of huge buffer overruns in config_test_file_read() and
  config_test_file_read_write() that could load 63K of file contents past
  the end of the buffer (on the stack).  Fortunately, these functions are
  only used by the config-test feature, never during normal operation.
Fixed a buffer overflow in find_address() that would overwrite a single byte
  in the caller's stack with a null byte when parsing BATV addresses.  From
  what I can tell, the effect of this bug would be to either truncate the
  parsed address or cause a segfault.
Added undo_softlimit() to try to increase the "soft" limits on address space,
  stack size and memory size to maximum if they are less than infinite (and
  squawk if they cannot be reset to maximum).  This will (hopefully) prevent
  problems caused by DJB's "softlimit" program, which is a useless piece of
  trash many qmail install guides *still* recommend using.
Fixed a bug in the logging code of tls_read() that was using an "error"
  message to log at "verbose" level.  The error message had more printf()
  format specifiers than the verbose logger was providing, which was leading
  to segfaults when the message was printed.  Many thanks to Konstanin for
  a lot of help tracking this one down.

Update to 5.0.0. From the changelog:

Rearranged the test scripts to put them in folders by category.  This just
  makes the directory listing a little more manageable.
Corrected some typos in the README file.  Thanks to John Mendoza for reporting
Fixed a very obscure bug in spamdyke_log(): on Linux systems (possibly only
  64-bit systems), vsyslog() occasionally will not print all the variable
  arguments.  One way was found to trigger this behavior -- when the
  rdns-blacklist-dir filter is activated from a configuration directory.
Fixed a bug in find_domain() that could cause segfaults when parsing certain
  invalid formats.  Thanks to Gary Gendel for reporting this one.
Added a backup/restore feature to the "run" script in the "tests" folder to
  save a copy of the most critical system and qmail files before running any
  scripts.  This is needed because some of the scripts alter those files and,
  if they don't run correctly or are cancelled, the originals are lost.
Added a "-skipcompile" flag to the "run" script in the "tests" folder to skip
  reconfiguring and recompiling all of the binaries when the script is run.
Changed the "run" script in the "tests" folder to empty qmail's queue before
  and after the tests are run.
Changed the "run" script in the "tests" folder to compare the current system
  and qmail configuration files to the latest backup after every script
  finishes.  If they don't match, the latest backup is restored.  If they
  still don't match, the script stops with an error.
Changed nihdns_query() to accept an optional "preferred" type of response.  If
  multiple types are queried, it will wait for at least one timeout period for
  an answer of that type to arrive instead of always accepting the first
  answer to arrive.  It will accept a saved answer before resending the
  queries, however.
NOT BACKWARDS COMPATIBLE: Changed nihdns_mx() to prefer an MX record over an A
  record, if both exist.  Given the choice, the MX record will be checked for
  validity and the A record will be ignored.  Thanks to Bruce Schreiber for
  suggesting this one.
Fixed filter_level() and smtp_filter() to disregard whitelisting and require
  authentication if the "filter-level" option is set to "require-auth", as the
  documentation says it should.  Thanks to Arne for reporting this one.
Changed nihdns_create_packet() to strip trailing dots from names before using
  them in DNS queries.  A trailing dot is the traditional way to tell libc's
  resolver not to append the local domain name and many sysadmins expect to
  have to use it.  Since spamdyke never appends the local domain and doesn't
  use libc's resolver, it isn't necessary and causes lookups to fail.  Thanks
  to Dossy Shiobara for reporting this one.
Changed middleman() to always send a "STARTTLS" response to "EHLO" as a
  continuation, never as the last line (only when spamdyke is inserting
  "STARTTLS").  This works around a bug in the Android mail client, which only
  looks for "STARTTLS" as a continuation.  Thanks to Jonas Pasche for writing
  about how to work around this bug on his blog.
NOT BACKWARDS COMPATIBLE: Changed the meaning of "whitelisted" to only exempt
  the connection from spamdyke's spam filters; whitelisting no longer allows
  the connection to relay mail.  This means spamdyke will now only set the
  RELAYCLIENT environment variable if the "relay-level" option is set to
  "allow-all".  Relaying must now be controlled through tcpserver or xinetd.
  Many thanks to Eric Shubert for suggesting and debating this with me.
NOT BACKWARDS COMPATIBLE: Removed the "access-file" and
  "rejection-text-access-denied" options because they were only needed for
  controlling relaying.  Also removed the test scripts that exercised them and
  modified many other test scripts that used them.
NOT BACKWARDS COMPATIBLE: Removed the "no-check" value from the "relay-level"
  option and changed the meaning of the "normal" value to use the logic
  previously assigned to "no-check".
Added the option "reject-sender" to take multiple values.  If the value
  "not-local" is given, the sender will be rejected if the domain name is not
  hosted locally.  If the value "authentication-mismatch" is given, the sender
  will be rejected if the sender address does not exactly match the username
  given during authentication (or if the authentication username is not an
  email address, the sender username must match the authentication username).
  If the value "authentication-domain-mismatch" is given, the sender will be
  rejected if the domain name is not part of the username given during
  authentication.  Thanks to Mark Frater for suggesting this one.
Added the options "rejection-text-sender-not-local" and
  "rejection-text-sender-authentication-mismatch" to set the rejection text
  given when the "reject-sender" option's filters are triggered.
NOT BACKWARDS COMPATIBLE: Removed the option "reject-missing-sender-mx" and
  folded its filter into the "reject-sender" filter's "no-mx" option.
  "rejection-text-missing-sender-mx" to "rejection-text-sender-no-mx".
  "reject-identical-sender-recipient" to "reject-recipient" with the value
  "same-as-sender".  The functionality remains the same.
  "rejection-text-identical-sender-recipient" to
NOT BACKWARDS COMPATIBLE: Renamed the option "local-domains-file" to
  "qmail-rcpthosts-file".  The naming has always been confusing, since qmail
  distinguishes between domains that should be accepted by qmail-smtpd during
  SMTP (rcpthosts) and domains that are actually hosted locally with mailboxes
  on the local filesystem (locals).  These options have always meant the
  former, but now that spamdyke needs to know both lists of domains, it's time
  to rename them.  This option is also now allowed in configuration
NOT BACKWARDS COMPATIBLE: Removed the option "local-domains-entry" because
  supplying domains that can be accepted during SMTP to spamdyke only (but
  not qmail) will cause inconsistent results during recipient validation.
  If a domain is to be accepted during SMTP, it should be added to the control
  files used by both spamdyke and qmail.
Added CDB searching code in cdb.[ch] to read DJB's "constant database" files
  during recipient validation.  The format of these files is claimed (by DJB)
  to be fast and efficient.  Don't believe the hype...
Added the option "qmail-morercpthosts-cdb" to allow CDB files to be provided
  that contain lists of domains for which mail should be accepted during SMTP.
  Does anyone actually use this qmail "feature"?
Poured over qmail's documentation and source code to figure out exactly how
  it determines where to deliver a message.  The documentation is frequently
  in error and extensive testing was required to discover the truth.  The
  resulting procedure is encapsulated in a flowchart in the documentation
Added the "generator" program to create test scripts to check every possible
  path through the recipient validation flowchart, both with spamdyke in place
  and without (to check the flowchart is correct).  A program to generate the
  scripts was required, since there are nearly 250K possible paths to test.
Added the value "invalid" to the option "reject-recipient" to check if a local
  recipient address exists before accepting a message.  This validation
  process uses the same logic as qmail when deciding whether/where to deliver
  a message, so no extra steps are needed to make this work (e.g. maintaining
  a list of valid addresses in a separate file).  If this process determines
  a local address is valid, delivery is guaranteed.  This option should
  eliminate qmail's habit of sending backscatter spam.
Added the value "unavailable" to the option "reject-recipient" to check if a
  local recipient is accepting mail at the moment.  Probably as a holdover
  from the elder days when people actually edited .qmail files by hand, qmail
  checks file permissions on files and folders before delivering a message.
  If they are set to certain values, qmail will queue the message until the
  permissions are fixed or bounce the message if is queued too long.  In these
  enlightened times, such permissions are more likely to be due to an error or
  oversight than deliberate intent.
Added the options "qmail-assign-cdb", "qmail-defaultdelivery-file",
  "qmail-envnoathost-file", "qmail-locals-file", "qmail-me-file",
  "qmail-percenthack-file" and "qmail-virtualdomains-file" to allow spamdyke
  to use different control files than qmail.  It's very unlikely anyone will
  ever need these options (and it would be unwise to use them), but they're
  available just in case.
Added the option "rejection-text-recipient-invalid" to set the rejection text
  when the "invalid" filter on "reject-recipient" is triggered.
Added the option "rejection-text-recipient-unavailable" to set the rejection
  text when the "unavailable" filter on "reject-recipient" is triggered.
Removed the function filter_recipient_local() and moved its logic into
Removed the function filter_recipient_relay() and moved its logic into
Changed the "help" option to just show a listing of available options without
  help text.
Added the "more-help" option to show the full listing of options with all help
Added the options "ip-relay-entry", "ip-relay-file", "rdns-relay-entry" and
  "rdns-relay-file" to allow relaying from specific IPs and/or rDNS names,
  since whitelisting no longer implies the ability to relay.  If any of these
  options are matched, the RELAYCLIENT variable will be set before qmail is
Created the "create_cdb" program to generate CDB files of arbitrary size,
  filled with random data, for testing spamdyke's CDB validation routines.
  create_cdb also has the ability to corrupt the generated CDB in seven ways;
  this makes for more specific testing than simply using a file of random
Removed all uses of the TESTSD_* environment variables from the test scripts
  and replaced them with appropriate invocations of dnsdummy.  This allows the
  test scripts to run without potential interference from external DNS
  changes and without needing a running spamdyke server to find example
Fixed smtp_filter() and middleman() to clear the list of saved recipient
  addresses after printing the log messages.  This prevents duplicate log
  messages when multiple email messages are delivered in the same connection.
  Thanks to Teodor Milkov and David Davidov for reporting this one.
Added the "-skippatched" and "-skipunpatched" flags to the "run" scripts to
  skip any tests that require a patched or unpatched version of qmail,
Fixed a minor bug in find_username() that would truncate the last character
  of the username when no domain is given.  This hasn't been a problem since
  spamdyke rejects recipient addresses without domain names anyway, but one
  of the recipient validation test scripts found it.
Added the option "tls-dhparams-file" option to read DH params from a file
  for creating ephemeral keys during SSL/TLS key negotiation.  Thanks to
  Marc Gregel for suggesting this one.
Changed all error messages to output the filename, function name and line
  number that generated them, just like the debug and excessive messages.
Added a new log level, LOG_LEVEL_CONFIG_TEST, for config-test error messages.
  The level is treated much the same as LOG_LEVEL_ERROR except the filename,
  function name and line numbers are not printed.
Added a new decision level, FILTER_DECISION_AUTHENTICATED for authenticated
  connections.  The filter routines use this level to distinguish between
  connections that should be unfiltered due to authentication versus
Added a new config option type: CONFIG_TYPE_ALIAS.  Options of this type are
  aliases for other options.  This eliminates the duplication of values and
  potential for oversights in the graylist/greylist options.
Added some code to the "run" script in the "tests" directory to try to detect
  core dumps.  Some of the tests will declare success even if spamdyke
  segfaults and cuts off the output prematurely.
Removed the unused functions reset_rejection() and skip_cfws().
Discovered spamdyke cannot read all the files it needs for recipient
  validation during normal operation because they are owned by different users
  with restrictive permissions and spamdyke does not run as root.  I'm not
  sure how I missed that, but it completely moots more than a year of work.
Moved all the recipient valiation code into an external program named
  "spamdyke-qrv".  This program is meant to only perform recipient validation
  and nothing else, so it should be safe to run as root (at least safer than
  running spamdyke as root).
Removed the options "qmail-assign-cdb", "qmail-defaultdelivery-file",
  "qmail-envnoathost-file", "qmail-locals-file", "qmail-me-file" and
  "qmail-percenthack-file" from spamdyke, since the recipient validation code
  is gone.
Added the option "recipient-validation-command" for passing the path to
  spamdyke-qrv, which will be called when recipient validation is needed.

Update to 4.3.0. From the changelog:

This version adds the ability to filter messages based on the content
of their headers. Please note that enabling this feature should
be accompanied by disabling the use of the "softlimit" program. In
addition to fixing some small bugs and a compiling error on Debian
7, it also fixes a series of major bugs that could lead to buffer
overflows. Depending on spamdyke's configuration, these could cause
remotely exploitable security holes. Please upgrade immediately!

Looks like there's a bug in the header blacklist filter. Don't
enable that filter yet.

  Fixed config-test message for a graylist domain folder when the domain is not
    in the list of local domains from ERROR to INFO. Thanks to Eric Shubert
    for reporting this one.
  Fixed a bunch of copy-and-paste errors in the option_list array in
    prepare_settings() where options were designated
  Fixed configure script errors and compilation warnings on Debian 7, which
    enables the new GCC flags -Waddress and -Wunused-but-set-variable by
    default.  Thanks to Steve Cole for reporting this one.
  Added some explanitory comments to spamdyke.h and spamdyke.c.
  Added FILTER_FLAG_RETAIN and modified middleman() to buffer any data as long
    as it is given.
  Added FILTER_FLAG_CHILD_RESPONSE_INTERCEPT and modified middleman() to discard
    any input from qmail when it is given.
  Added FILTER_FLAG_DATA_CAPTURE and modified middleman() to capture qmail's
    response to the end of the message data when it is given.
  Fixed output_writeln() to send the data in bursts if more than one line is
    given and no CRs need to be inserted.  Previously, all data was sent
    line-by-line, even though middleman() was trying to send bursts of data when
  Changed middleman() to buffer the names of the accepted recipients until after
    the message data is sent, then check qmail's response to the message body
    and print ALLOWED/DENIED for each recipient accordingly, along with the text
    of qmail's response.
  Added the options header-blacklist-entry and header-blacklist-file to block
    messages based on the contents of their headers.
  Added the option rejection-text-header-blacklist to control the message from
    the header blacklist filter.
  Added a flag to smtpdummy to force it to reject all message content with an
  Added a more complete usage message to smtpdummy.
  Fixed a number of very serious errors in the usage of snprintf()/vsnprintf().
    The return value was being used as the length of the string printed into
    the buffer, but the return value really indicates the length of the string
    that *could* be printed if the buffer were of infinite size. Because the
    returned value could be larger than the buffer's size, this meant remotely
    exploitable buffer overflows were possible, depending on spamdyke's
  Added options to smtpdummy to make it appear to process authentication (and
    unconditionally succeed or fail).
  Changed the ALLOWED log message to show the text given by qmail when the
    message is accepted.

Update to 4.2.1. From the changelog:

This version extends the log messages to show why a blacklist is
matched. It also fixes a few minor bugs.

  Added a filter to sendrecv so input containing "\r\n" will be
    translated into CRLF without being interpreted as a line
    terminator (so multiple commands can be sent in a single "packet")
    and input containing "\0" will be translated into NULL bytes
    so NULL characters don't have to be embedded in the test scripts.
  Added support for the RSET command to smtpdummy.
  Added a "priority" field to the input file for dnsdummy to force
    some responses to be sent after others, no matter what order
    they were received.
  Fixed nihdns_mx() to query names for A records using the query
    types configured for MX queries, not A queries. Thanks to Eric
    Shubert for reporting this one.
  Changed smtp_filter() and middleman() to discard any buffered
    input after TLS is started. This prevents the injection of
    commands into a secure session by sending extra input in the
    same packet as the "STARTTLS" command. Not really a security
    problem but good practice anyway. Thanks to Eric Shubert for
    reporting this one.
  Fixed a bug in examine_entry() that was cutting off 1-3 characters
    from the end of target_entry every time it was called.
  Changed check_ip_in_rdns_keyword() to return the line number of
    the matching file as its return value and the name of the
    matchine file in a reference variable.
  Added reject_reason and strlen_reject_reason to struct rejection_data
    to allow the triggered filter to return some text to indicate
    why it triggered.
  Changed set_rejection() to accept new parameters to set reason
    text within the rejection structure if available.
  Changed set_rejection() to accept a new parameter to append to
    the rejection text if available.
  Added reset_rejection() to change either the rejection text or
    the reason text within an existing rejection_data structure
    without erasing previously-set values.
  Changed nihdns_rbl(), check_dnsrbl() and check_rhsbl() not to
    accept a format string or build part of the rejection message.
    That job belongs to the caller(s).
  Changed filter_rdns_blacklist(), filter_rdns_blacklist_file(),
    filter_rdns_blacklist_dir(), filter_ip_blacklist(),
    filter_ip_in_rdns_blacklist(), filter_dns_rbl(), filter_dns_rhsbl(),
    filter_sender_blacklist(), filter_sender_rhsbl() and
    filter_recipient_blacklist() to save the reason for their
    rejection in the reject_reason variable in rejection_data.
  Changed the log messages showing ALLOWED/DENIED to always output
    the "reason:" field and fill it with the text returned by the
    triggered filter so the sysadmin can figure out what happened
    or "(empty)" if no text was saved. Thanks to Eric Shubert for
    suggesting this one.
  Changed the way DNS timeout values are read from the configuration
    file, the command line, /etc/resolv.conf and the environment
    so that values given in the config file or on the command line
    are not overridden by values in /etc/resolv.conf or the
    environment. Thanks to Teodor Milkov for reporting this one.
  Changed the reject-empty-rdns filter, the IP-related black/whitelist
    filters and the IP-related RBL filters to skip their tests if
    the incoming IP address is This is for connections
    from IPv6 hosts -- those filters can be skipped until full IPv6
    support can be added. Thanks to Daniel Anliker for suggesting
    is handled by smtp_filter() and middleman() so a transient
    non-rejection (e.g a recipient whitelist) isn't held over to
    later recipients. The interaction between the recipient whitelist
    and the graylist filter was fixed in version 4.0.0 but an issue
    still remained between recipient whitelists and other non-transient
    rejections like the missing rDNS filter. Thanks to bischowski
    for reporting this one.
  Changed smtpdummy to use memchr() instead of strchr() so testing
    input with NULL bytes will work correctly.

Update to 4.2.0. From the changelog:

  Changed read_file() to return the number of usable lines read, instead of the
    total number of lines (including comments and whitespace).
  Fixed a huge thinko in many calls to read_file() -- when the function returns
    0, the returned value is NULL.  This was causing spamdyke to crash when no
    content was read from files by "dns-blacklist-file", "dns-whitelist-file",
    "rhs-blacklist-file", "rhs-whitelist-file" and "hostname-file".  Thanks
    to David Stiller for reporting this one and providing a lot of help in
    tracking it down.
  Added the option "tls-cipher-list" for specifying the list of ciphers to use
    in SSL/TLS connections.  This won't be an option many people will ever use,
    but in specific setups it is required.  Thanks to Chris Boulton for
    suggesting this one and producing a patch to implement it.
  Added a new value to "tls-level": "smtp-no-passthrough" to allow spamdyke to
    offer TLS but prevent it from passing TLS through to qmail if the SSL
    library cannot be initialized for some reason.
  Fixed a bug in smtp_filter that allowed open relaying when spamdyke was
    configured with "local-domains-entry" instead of "local-domains-file".
  Moved code from do_spamdyke() that set stdin and stdout sockets to
    non-blocking into tls_read() and tls_write() instead.  Setting the sockets
    to non-blocking through the entire run was causing some strange behavior
    where logging would stop after a series of large inputs.
  Refactored the address parser (yet again) to fix a bug that wasn't handling
    routing addresses properly.  Thanks to Chris Boulton for reporting this one.
  Fixed process_config_file() to not reset a "multiple" value to default if it
    was deliberately cleared during configuration.
  Fixed prepare_settings() to initialize all default values before processing
    the command line or configuration files so a "multiple" value can be cleared
    during configuration.
  Fixed to use a gcc #pragma command to treat format warnings as
    errors instead of relying on AC_LANG_WERROR (which doesn't always work).
  Added the options "dns-query-type-a", "dns-query-type-mx",
    "dns-query-type-ptr" and "dns-query-type-rbl" to limit the types of DNS
    queries that can be sent for different purposes.  Thanks to Teodor Milkov
    for suggesting this one.
  Fixed a bug that caused a timeout whenever a post-RCPT filter is triggered
    on a non-local address.  spamdyke is supposed to close the connection to
    qmail and wait for its exit, but instead was just waiting for its exit,
    leading to unnecessary timeouts.  Thanks to Ulrich C. Manns for reporting
    this one.
  Fixed a typo in policy.php.example.  Thanks to Richard Lamse for reporting
    this one.
  Fixed compiler warnings on Fedora 11.  Thanks to Ertan Orhan for reporting
    this one.
  Fixed a bug in sendrecv where an uninitialized variable was causing erroneous
    stalls and timeouts in CentOS 5.5.

Update to 4.1.0. From the changelog:

Changed the option "hostname-file" to read /var/qmail/control/me by default.
Added the option "dns-resolv-conf" to read the nameserver from a file other
  than /etc/resolv.conf if necessary.  Multiple files can be read, if needed.
Changed all uses of strncpy() to memcpy() because strncpy() will fill the
  remainder of the destination buffer with zeroes if the source string is
  too short.  This is not needed because all strings are being explicitly
  terminated after copies anyway.
Added two new parameters to search_file() to allow the matching line data to
  be returned to the caller.
Changed process_access() to save the contents of the RELAYCLIENT environment
  variable, if set.
Added the timefilter program to the utils folder.
Reversed a small change to spamdyke_log() made 4.0.8 that will prevent buffer
  overflows in obscure situations.
Changed is_ip_in_name() to look for more patterns of IP addresses in rDNS
  names:,, and
  Thanks to Eduard Svarc for suggesting this one.
Changed the syslog output to include an "encryption:" tag at the end that
  shows the current status of TLS/SSL encryption.  Thanks to Eric Shubert for
  suggesting this one.
Added a "-R" option to smtpdummy so it will reject all recipients.
Completely rewrote find_address() to completely conform to RFC 2822 when
  parsing addresses, including quoting, comments, folded whitespace and
  all the rest.
Added the option "reject-identical-sender-recipient" to block any messages
  where the sender and recipient are the same.  Thanks to almost everyone
  on the mailing list for suggesting this one.
Changed nihdns_mx() to tolerate MX records that contain IP addresses (illegal)
  instead of names.
Fixed to use the CPPFLAGS variable from the "configure" script, if
  the user provided it in an environment variable.  Thanks to Iavor Stoev for
  reporting this one.
Fixed the "configure" script to correctly include header files on FreeBSD 7.0.
  Thanks to Andrew Khon for reporting this one.
Added a "-S" flag to sendrecv to prevent it from starting a TLS session when
  it sees "STARTTLS".
Improved sendrecv's usage display to document what each option does.
Changed do_spamdyke() to set the stdin and stdout file descriptors to
  nonblocking before calling middleman().  This works around a bug in the SSL
  library that will block forever waiting for input, even after SSL_pending()
  and/or select() has already indicated the socket is ready.  Thanks to
  Teodor Milkov for identifying this problem more than a year ago and trog for
  producing a patch to fix it!
Fixed process_config_file() to reject configuration file lines with
  bad/missing characters.
Fixed process_config_file() to print an "unknown option" error message instead
  of an "illegal option" message when an unknown option is found in a
  configuration file.
Added option "rejection-text-identical-sender-recipient" to set the rejection
  message for the identical sender/recipient filter.
Created dnsdummy to simulate a nameserver but exit after a short while for
  testing spamdyke's DNS routines.
Converted all DNS-related tests to use dnsdummy and removed all references to and  This will also allow the removal of the
  (hundreds of) bogus entries from the zone file.
Removed the use of getprotobyname() from dns.c and used the defined protocol
  values in netinet/in.h.
Changed nihdns_query() to retry DNS queries via TCP if the response received
  via UDP has the "truncation" flag set (indicating the answers are too large
  for a UDP packet).  Thanks to Roland Moelle for suggesting this one.
Added option "dns-tcp" to control if spamdyke will retry DNS queries via TCP.
Added option "dns-spoof" to control if spamdyke will attempt to detect DNS
  spoofing and, if so, what it should do about it.
Fixed smtp_filter() to offer and accept SMTP AUTH (when appropriate) even if
  the connection is already whitelisted.  Thanks to Ratko Rudic for
  reporting this one.

Update to 4.0.8. From the changelog:

Changed spamdyke_log() to send all messages to stderr (when appropriate) using
  a single call to vfprintf() by adding newline characters and PID prefixes to
  the format before outputting anything.  This is necessary to work around a
  problem with the design of DJB's multilog program, which uses a single pipe
  to accept input from all processes and thus cannot keep log messages
  separate.  This means partial output from some spamdyke processes could
  overlap output from other spamdyke processes when the load rises (a race
  condition).  Thanks to Philip Nix Guru for reporting this one.

Update to 4.0.7. From the changelog:

VERSION 4.0.7: 10/17/2008
  Changed to compile configuration.c in two steps: first use gcc
    to produce the preprocessed source, then use gcc to compile it.  For some
    reason, gcc crashes on FreeBSD 6.0 when the file is compiled in one step.
    Thanks to K. Shantanu for reporting this one and Felix Buenemann for
    suggesting the fix.

VERSION 4.0.6: 10/16/2008
  Fixed a problem in examine_ip_in_rdns_keyword_entry() that was not correctly
    terminating the end of the keyword buffer, causing strstr() to search too
    far, leading to false negatives (and potentially segmentation faults).
    Thanks to Erald Troja for reporting this one.
  Fixed another problem in middleman() that was not correctly replacing _all_
    of qmail's AUTH advertisements when the "smtp-auth-level" option is
    "always" or "always-encrypted".  Thanks to Youri Kravatsky for reporting
    this one (again).
  Fixed the fix to a bug in nihdns_query() that was setting
    return_target_name_index to 0 in all cases.  This was causing log messages
    to print the first RBL/RHSBL name instead of the one that actually matched.
    Thanks to Arthur Girardi for reporting this one (again).
  Reverted a change from 4.0.5 -- removing the usable_buf_input flag from
    middleman() meant could only tell if there was input in the buffer, not if
    any of it was actually usable.  If the remote server delays sending its
    data for any reason, middleman() will loop rapidly to continually check if
    its buffered data can be sent to qmail.  Removing the flag meant spamdyke
    was consuming 100% CPU while receiving messages with large attachments.
    Thanks to Paulo Henrique Fonseca for reporting this one.
  Added the "cputime" program to the "tests" folder to measure the CPU time
    used by a process.  Neither the shell "time" command nor the POSIX "time"
    command seem to do that.
  Changed sendrecv to always wait() for its child processes so CPU accounting
    will be performed correctly.
  Fixed check_rhsbl() to correctly return the name of the matching RHSBL instead
    of an index that could be beyond the end of the array.
    to make none of them equal to 0.  Because the "log-target" option is a
    CONFIG_TYPE_NAME_MULTIPLE option, it is set to 0 until the command line and
    all configuration files are parsed.  When LOG_USE_CONFIG_TEST is 0, the
    progress messages from process_config_file() are sent to stderr until the
    configuration file is completely loaded.  For Plesk users, xinetd sends
    stderr to the network connection, so the remote server gets the output.
    Thanks to Arthur Girdari for reporting this one and helping track it down.

Update to 4.0.5. From the changelog:

- If the idle timeout is not configured, it is now set to 20 minutes
    after qmail exits to prevent never-ending spamdyke processing.
    Thanks to Matthew Kettlewell for reporting this one.
- Fixed the AUTH advertisements to display correctly when
    "smtp-auth-level" is "always" or "always-encrypted". Thanks
    to Youri Kravatsky for reporting this one.
- Fixed a sequencing error that would cause qmail to exit prematurely,
    even if valid recipients could still possibly be given. Thanks
    to David Stiller for reporting this one.
- Fixed the handling of unencoded null characters in messages
    (technically not legal) so spamdyke does become confused and
    timeout. Thanks to Arthur Girardi for reporting this one.
- Fixed an issue in the DNS query code that was setting array indexes
    beyond the end of the array, resulting in garbage log messages
    and segmentation faults. Thanks to Arthur Girardi for reporting
    this one.
- Fixed verbose logging in the RHSBL filter to print the correct
    log message. Thanks to Arthur Girardi for reporting this one.
- Rewrote the address parser to correctly handle strange/invalid
    email addresses. Thanks to Erald Troja for reporting this one.
- Fixed a serious error in the code that loads array values from
    files that was returning pointers to unallocated memory, causing
    segmentation faults. Many, many thanks to David Stiller for
    reporting this one and providing tons of help to nail it down.
- Fixed a serious error that was attempting to move data by
    dereferencing the NULL address when the remote server disconnected
    unexpectedly, causing segmentation faults. Many, many thanks

    help to nail it down.

Update to 4.0.4. From the changelog:

Moved the code for loading configuration files into prepare_settings() from

  being set before the configuration files were read, the syslog option
  could be incorrectly set, even if stderr was specified in a file.
  Thanks to Eric Shubert for reporting this one.
Changed the configure script to detect environments where printf()/scanf()
  use "%ld" for 64-bit integers instead of "%lld" (CentOS 64-bit).  This
  wouldn't be necessary if the gcc authors could grasp the idea that
  "long int" and "long long int" may be interchangable and not emit warnings.

Update to 3.1.8. From the changelog:

This version fixes a bug with the recipient filters that could allow
a clever sender to use a spamdyke-protected server as an open relay.
The sequence of commands are not legal SMTP, so the sender would
have to know the server was running a vulnerable version of spamdyke
to exploit this bug.  Thanks to Mirko Buffoni for reporting this

This version also fixes two problems with the idle timeout filter.
The first could cause the connection to be rejected because qmail
is slow to respond (which isn't fair).  The second was a tricky
issue where large messages from fast remote servers could be
improperly rejected because the idle timer wasn't being reset.
Thanks to Eric Shubert for reporting and helping me fix this one.

This version also fixes two compiling problems.  The first was a
problem in the "configure" script on older Gentoo installations
running gcc 3.4.6 that was treating a preprocessor warning as an
error.  Thanks to Thorsten Puzich for reporting and helping me fix
this one.  The second was a problem with CentOS 3.8, which doesn't
install the OpenSSL headers in the system include folder.  Thanks
to Bruce Schreiber for reporting this one.

VERSION 3.1.6 -- 2/11/2008
  Fixed a serious bug in middleman() -- when the remote server sent its message
    data and QUIT command in a burst and disconnected before spamdyke read() all
    of the data, the last data returned from read() was printed twice.  This
    could cause message corruption, especially in the case of attachments.
  Fixed a serious bug in middleman() -- when the remote server sent its data
    in bursts of 4096 bytes AND there were two lines of text in the data
    AND the 4096th character was not a newline AND there was a delay between the
    data bursts, memmove()ing the buffered data was causing corruption because
    the moved data was not being properly re-terminated.  While processing the
    remaining buffered data (and waiting for another burst from the remote
    server), strchr() would seek past the end of the data to an old newline
    character and middleman() would erroneously conclude the next line of data
    was complete, ready for processing.  Many thanks to Andreas Galatis and
    Dragomir Denev for reporting and helping me reproduce this one.
  Added a -W flag to sendrecv to introduce a delay between message data bursts.
  Added a -o flag to smtpdummy to save the message data to a file.

VERSION 3.1.5 -- 1/22/2008
  Fixed sendrecv to correctly process corrupted TLS negotiations instead of
    covering up bugs in spamdyke.
  Fixed spamdyke to not add garbage output at the beginning of TLS passthrough
    negotiations.  This was causing SSL handshakes to fail.  Thanks to Ronnie
    Tartar for reporting this one.

VERSION 3.1.4 -- 1/21/2008
  Fixed all of the Makefiles to remove a symbols directory Leopard's gcc seems
    to create when compiling in debug mode.
  Fixed middleman() to log the timeout message only once.
  Fixed middleman() to not expect input from the child process when the child
    process' input is being ignored or after the child process has exited.
  Fixed middleman() to correctly handle a rare situation -- when the child
    process was too slow responding that spamdyke's idle timeout was passed
    AND spamdyke was processing TLS data AND there was still data in the SSL
    buffer, spamdyke would loop infinitely, consuming 100% CPU.  This was a
    very tricky bug to find and fix.  Thanks to Pablo Gonzalez and Paolo for
    reporting this one and helping me debug it.
  Fixed middleman() to send message data to the child process line-by-line,
    even when the buffer is full.
  Added a new test program: smtpdummy.  This one simulates an SMTP server and
    can add delays after specific commands.
  Changed sendrecv to use a 64K buffer for input and output data.
  Changed sendrecv to kill the its child process after its timeout expires.
  Changed sendrecv to optionally continue sending data in bursts after the end
    for the message data.  Some mail servers do this.
  Changed sendrecv to deliberately send corrupt data while TLS is active.
  Changed test regression_009 to build its message payload at runtime instead
    of including a 0.75M file.  This file was unnecesarily increasing the size
    of the spamdyke tarball.
  Fixed compiling on Solaris.  Again.  Thanks to Davide Bozzelli for reporting
    this.  Again.  Sigh.

VERSION 3.1.3 -- 1/3/2008
  Fixed the format string LOG_INFO_DNS_TXT to assign the parameters correctly
    and prevent bus errors when the DNS response text is long.  Thanks to
    Stephan Rosenke for reporting this one.

VERSION 3.1.2 -- 12/11/2007
  Fixed smtp_filter() to set a flag after some SMTP commands to force
    middleman() to wait for input from the child process before proceeding.
    Some (nonspammer) mail servers send their data in bursts without waiting for
    responses.  This was causing spamdyke to skip logging (but not filtering)
    if the DATA command was sent in a burst with RCPT TO.  Thanks to Sebastien
    Guilbaud and Bucky Carr for reporting this one.
  Added a "-b" flag to sendrecv to simulate servers that send their message data
    (but not their SMTP commands) in bursts.

VERSION 3.1.1 -- 11/12/2007
  Added excessive logging to search_domain_directory() to log the directory
    search pattern.
  Changed all calls to spamdyke_log() to use the macros SPAMDYKE_LOG_NONE(),
    SPAMDYKE_LOG_EXCESSIVE() instead.  The macro tests the current log level
    without forcing a function call and also paves the way toward eliminating
    some logging code at compile-time.
  Fixed process_access() to correctly search for the RELAYCLIENT variable in
    spamdyke's environment.  Thanks to Steve Cole for reporting this one.

VERSION 3.1.0 -- 11/5/2007
  Changed the "graylist-dir" and "no-graylist-dir" options to take multiple
    directories for servers that are hosting so many domains that they can't
    create enough domain folders in one place (wow).
  Added minimum and maximum values to all integer options and changed
    set_config_value() to generate error messages when values are out of range.
  Change usage() to print minimum and maximum integer values.
  Alphabetized the option list by long option name and changed
    process_config_file() to use a binary search algorithm when identifying
    directives, a theoretical improvement from O(n/2) to O(log n).
  Changed prepare_settings() to create an array of options indexed by the short
    option code.  This introduces some constant-time work (O(1)) and greater
    memory usage.
  Changed process_command_line() to use the indexed array of options,
    theoretically reducing command line parsing work from O(n/2) to O(1).
    This is a win if the command line has many parameters or if it has
    parameters that are near the end of the unindexed option array.
    Testing confirms a small performance gain.
  Added command line options "config-test-smtpauth-username" and
  Changed config_test_smtpauth() to run the authentication command(s) if a
    username and password are provided.  This incorporates the functionality of
    checkpassword into spamdyke.
  Added the command line option "config-test-user" to change user and group IDs
    before running the configuration tests.  This makes it easier to simulate
    running as the mail server.
  Changed process_config_file() and process_command_line() to print errors and
    stop when they encounter an option that is not legal in that location.  At
    the moment, "help", "version", "config-test",
    "config-test-smtpauth-username", "config-test-smtpauth-password" and
    "config-test-user" are not valid in files; all options are valid on the
    command line.
  Changed config_test_dir_read() and config_test_graylist() to never examine the
    "." or ".." folders, even if readdir() and/or stat() report they are not
    folders.  Thanks to Paulo Henrique for reporting this one.
  Changed set_config_value() to remove trailing slashes from directory paths.
  Added test_spamdyke_binary() to check if the spamdyke binary is setuid root
    (it should not be).
  Renamed test_settings() to config_test().
  Moved all of the configuration test functions to config_test.[ch] -- they were
    cluttering up configuration.c.
  Made a few small updates to the help message text.
  Added additional vchkpw exit codes to exec_checkpassword() to explain why
    vchkpw exited, since it doesn't follow DJB's published checkpassword API.
  Moved md5.[ch] from the "utils" folder to the "spamdyke" folder and updated
    Makefile to compile them into spamdyke.
  Removed passwordcheck from the "utils" folder since spamdyke now contains its
  Added a README file to the "utils" folder to answer the biggest FAQ about
    those utilities.
  Fixed exec_command() to connect the output pipe to the child process's stdin
    instead of file descriptor 3.  The bug was due to copying
    exec_checkpassword() and forgetting to change the value.
  Renamed exec_checkpassword() to exec_checkpassword_argv() and changed its
    arguments to expect a filename and an argument array.
  Added exec_checkpassword() to parse a command string into an argument array
    and call exec_checkpassword_argv().
  Renamed exec_command() to exec_command_argv() and changed its
    arguments to expect a filename and an argument array.
  Added exec_command() to parse a command string into an argument array
    and call exec_command_argv().
  Fixed numerous bugs in exec_command_argv() that were preventing it from
    actually gathering any input from the child process.
  Changed exec_command_argv() and exec_checkpassword_argv() to always log their
    child process errors to syslog, regardless of the user's preferences.
    Otherwise, the errors will be lost.
  Added the function find_path() to search the PATH for the given command
    without executing it.
  Changed exec_command_argv() and exec_checkpassword_argv() to use find_path()
    to locate the executable before fork()ing to catch typos.  The child
    processes then use execve() to execute the command instead of exec_path().
    Otherwise, the parent has a hard time determining that the child process
    quit because the command path was invalid.
  Changed exec_command_argv() and exec_checkpassword_argv() not to wait
    indefinitely for the child to exit after the timeout expires.
  Changed dns_txt(), dns_ptr_lookup() and dns_mx() to limit the total number of
    queries they will recursively perform.  This is to prevent a DoS situation
    where some domain has an unreasonable number of chained (non-circular) CNAME
    records.  The limit is (arbitrarily) set at 16.
  Added the function config_test_child_capabilities() to test the qmail binary
    for SMTP AUTH and TLS patches.  Depending on what is found, recommendations
    for spamdyke flags are made.
  Changed check_rdns_keywords() to allow top-level domains (like .com) to be
    used as keywords.  This allows a way to reject connections from remote
    servers with rDNS names that contain the IP address and a two-letter country
    code.  Unlike check_country_code(), specific country codes can now be
  Fixed do_spamdyke() not to wait indefinitely for all child processes to exit.
    This behavior was causing problems with DJB's recordio because recordio
    fork()s and uses its parent process to exec() spamdyke.  This is very
    unusual.  Changing wait(NULL) to waitpid() fixes the problem.  Thanks to
    Bob Hutchinson for reporting this one.
  Added dns_initialize() and dns_get() to perform DNS queries by sending UDP
    packets instead of using the resolver library to do it.  The resolver
    functions are just too slow and they try to do too much unnecessary work.
    dns_get() performs multiple requests for records (one for each kind of
    desired record) and, if no responses are received, sends requests to the
    secondary nameservers as well.  Timeouts and retransmission times can now
    be controlled.  This has resulted in a significant speedup in DNS
    resolutions; testing shows as much as a 10x performance increase in some
  Changed dns_txt(), dns_ptr_lookup() and dns_mx() to search all of the answers
    for the desired answer type before recursively querying CNAME answers.  Some
    nameservers always put the CNAME answers first, even if other answer types
    are also given.  This should allow spamdyke to find answers faster when
    domain admins have used a lot of CNAMEs.
  Added dns_a() to perform A record queries and changed all uses of
    gethostbyname() to use dns_a() instead.
  Changed dnsa, dnsmx, dnsns, dnsptr, dnssoa and dnstxt in the "utils" folder to
    only perform their specific queries, not ask for CNAME records as well.
  Changed dnsa, dnsmx, dnsns, dnsptr, dnssoa and dnstxt in the "utils" folder to
    send their own UDP packets instead of using the resolver library.
  Added dnscname to the "utils" folder to perform CNAME queries.
  Added dnsany to the "utils" folder to perform ANY queries and perform
    recursive CNAME lookups.
  Added "log-target" option to allow logging to stderr instead of syslog.  Some
    people apparently like using the qmail-style "multilog" instead of syslog.
    I can't understand why but I'm here to serve.  Thanks to John Hallam for
    suggesting this one.
  Changed all of the error messages about unexpected file types to specify what
    file type was found -- "non-regular file" was too vague to be useful.
  Changed the header in the files created by full logging to include the
    spamdyke version.
  Changed tls_end_inner() to use SSL_get_shutdown() to see if a shutdown signal
    has already been received.  If SSL_shutdown() is used on a closed file
    descriptor, spamdyke will crash with SIGPIPE.
  Changed all instances of read(), write(), SSL_read() and SSL_write() to read
    or write as many bytes as possible in each call.  This should provide a
    significant performance increase.  The single-byte read()s and write()s
    were only used because I had badly misunderstood the relationship between
    select() and read()/write() -- blocking only occurs when select() indicates
    a file descriptor is not ready.  If it is ready, read() and write() will
    handle as many bytes as they can without blocking.  Thanks to Trog for
    setting me straight on this one.
  Rewrote most of sendrecv in the "tests" folder to use a multi-byte read().
    Also took the opportunity to make sendrecv much faster and more polite, so
    it doesn't consume 100% CPU while waiting for qmail output.
  Fixed compiling errors on 64 bit Linux systems (Debian Etch x86_64 and Gentoo
    AMD64).  Thanks to Juha-Pekka Jarvenpaa and FireBall for reporting this.
  Added config_test_file_type() to use stat() to find a file's type if readdir()
    either doesn't report it (Solaris) or reports "unknown" for all files (XFS).
    Thanks to Paulo Henrique for reporting this one.
  Fixed compiling errors on Solaris.  Thanks to Limperis Antonis for reporting
  Changed the logging severity of the "unable to write X bytes to file
    descriptor" to debug instead of error.  99% of the time, the error occurs
    because the remote client disconnected unexpectedly and there's nothing
    the administrator can do about it anyway.
  Changed do_spamdyke() to ignore SIGPIPE signals.
  Changed do_spamdyke(), exec_command_argv() and exec_command_checkpassword()
    to change the SIGPIPE signal handler back to default for child processes
    after fork()ing but before exec()ing.
  Added a new logging level: excessive (4).  It's to be used for printing very
    detailed debugging statements.
  Changed process_access() to permit access when no matching lines are found in
    the access file.  Although DJB's tcprules documentation doesn't explicitly
    say so, no matching lines should allow access.  Thanks to Steve Cole for
    reporting this one.

VERSION 3.0.1 -- 9/12/2007
  Fixed "configure" to remove the "_beta1" tag from the version number.  That
    should never have been published.
  Changed usage() to show that optional values to long commands must be
    separated by an equals sign.  getopt_long() is really becoming a hassle.
    Thanks to Richard Kreider for reporting this one.
  Fixed find_address() to accept addresses that aren't correctly delimited with
    <> characters and/or have multiple (illegal) spaces after the colon.  Thanks
    to Davide Bozzelli for reporting this one.
  Fixed prepare_settings() to set the idle timeout seconds to the correct
    variable instead of setting the connection timeout variable.  Thanks to
    Carlo Blohm for reporting this one.
  Fixed smtp_filter() to print the rejection message to HELO and EHLO, even if
    those commands appear in an improper place in the protocol.
  Fixed smtp_filter() to print the rejection message with an error code in
    response to STARTTLS if the command is given in an improper place in the
  Added some regression tests to find these bugs in the future.
  Fixed the usage statement in sendrecv to show the -w flag.

VERSION 3.0.0 -- 9/11/2007
  Added command line options never-graylist-rdns-dir, always-graylist-rdns-dir
    and rdns-whitelist-dir to search domain directory structures just like
  Added the command line option rdns-blacklist-file to search a file just like
  Moved the command line option labels into configuration.c so they can be
    shared with the config file parser.
  Changed process_command_line() to build the list of short options from the
    list of long options instead of hardcoding them.  Less maintenance this way.
  Modified check_rdns_keywords(), search_file() and search_tcprules_file() to
    correctly track line numbers and return the matching line number instead of
    just 1.
  Changed logging to allow the amount of information to be turned up or down.
    This should make spamdyke less chatty in the syslog for small errors.
  Modified smtp_filter() and run_tests() to report the matching filename and
    line number from check_rdns_keywords(), search_file() and
    search_tcprules_file() in syslog if the logging level is high enough.
  Fixed find_address() to locate the real email address and ignore BATV tags,
    relay paths and bang paths.  Thanks to Walter Russo for reporting this one
  Changed middleman() to obey minimums and maximums for the amount of time to
    select() for traffic.  If spamdyke waits too long, the qmail process might
    not get wait()ed for a while, leaving a lot of defunct/zombie processes
    around.  On a busy server, this could be a problem.  Thanks to Jason M for
    reporting this one.
  Added process_config_file() to process configuration files instead of
    requiring all configuration to be done on the command line.  At the moment,
    the file just uses the same (long option) directives as the command line.
  Added test_settings() to run tests on every configuration option and
    (hopefully) identify misconfigurations before someone makes them on a live
  Added the command line option "config-test" to run test_settings().
  Renamed log_writeln() and log_write_rejection() to output_writeln() and
    output_write_rejection(), respectively, to make it clearer what they're
  Changed smtp_filter() to allow multiple authentication attempts.  Some
    clients retry authentication several times, presumably to deal with servers
    that can't use the authentication method they prefer.
  Changed middleman() to collect (and send) whole lines of input instead of
    single characters.  Single character write()s were causing problems with
    Nagios and Windows clients.
  Changed output_write_rejection() to create a single output line and send it
    to output_writeln() all at once instead of sending a piece at a time.  This
    keeps packets together for stupid Windows clients that just can't handle
    reassembling TCP packets correctly.
  Changed main() to always run spamdyke (as opposed to starting qmail without
    spamdyke listening) even if a whitelist is matched.  This way, spamdyke
    can report all traffic to syslog, not just traffic that _may_ be filtered.
  Changed smtp_filter() and middleman() to catch the return codes from qmail
    when the remote client gives the recipient address.  Now, if spamdyke
    doesn't block the recipient command but qmail does (e.g. for relaying),
    spamdyke will log the correct message.
  Incorporated GNU autoconf to create a "configure" script for spamdyke and the
    "utils" folder.  The days of "make no_tls" and "make bsd" are thankfully
  Renamed all of the test folders to group them by function so it's easier to
    see what tests exist.  Sequential numbers just weren't working.
  Changed dns_mx() to lookup the MX record before returning success.  This means
    the sender MX filter now requires a mail exchanger record _and_ at least one
    mail exchanger must have an IP address.  Before, the MX record was enough,
    even if there was no corresponding A record.
  Changed usage() to read the options and help text from get_spamdyke_options()
    in configuration.c so the help message won't ever be out of sync with the
    available options again.
  Added the command line option "tls-privatekey-password-file" to allow the SSL
    private key password to be read from a file instead of the command line.
    This way, the password isn't visible to everyone who can view a process
  Changed search_file(), search_tcprules_file() and check_rdns_keywords() so
    they no longer build their fscanf() patterns into a stack variable but
    instead use a literal search pattern assembled at compile time with
  Added the command line options "hostname-file" and "hostname-command" to
    support reading the local hostname from a file or from a command (e.g.
    "hostname -f") instead of forcing it to be specified on the command line.
  Changed middleman() and smtp_filter() to always monitor and trust
    authentication carried out by qmail, even if "smtp-auth-command" was not
    given.  This means spamdyke will always disable its filters for
    authenticated users even if it can't check the authentication itself.
    I'm not sure why I didn't design spamdyke this way in the first place.
  Added command line options recipient-whitelist-file and sender-whitelist-file
    so specific sender and recipient addresses can bypass the filters.  Sender
    addresses are very easy to fake and recipient addresses are, of course,
    known to spammers, so both of these options are ill-advised.  I've only
    added them due to popular demand.
  Added command line option check-rhsbl to check righthand-side blacklists.
    Both the server's rDNS domain name and the sender's email domain name are
  Added command line options check-dns-whitelist and check-rhs-whitelist to
    allow DNS RBLs and RHSBLs to act as whitelists instead of blacklists.
    Anyone using DNS-based blacklists _and_ whitelists had better have some
    seriously fast DNS servers.
  Changed dns_txt(), dns_mx() and dns_ptr_lookup() to pass a stack of previous
    queries whenever they recursively lookup CNAME records, to prevent a cylical
    CNAME structure from leading to infinite recursion.
  NOT BACKWARDS COMPATIBLE: Changed the syslog entry format: renamed "origin" to
    "origin_ip", added "origin_rdns:" before the rDNS name, added "auth:"
    before the authenticated username and added "reason:" before the rejection
    reason when a timeout occurs.
  Changed process_command_line() to assume the remote IP address is if
    the environment variable TCPREMOTEIP is not set.
  Added a ton more test scripts for all of the new options and for testing
    config files.
  Added dnsa, dnsns and dnssoa to the "utils" folder for performing DNS queries
    of A, NS and SOA records, respectively.  Wouldn't it be AMAZING if the
    libc maintainers added standard functions to do these queries?!
  NOT BACKWARDS COMPATIBLE: Changed the "flag" options to take optional
    arguments instead of simply assuming "true" when the option was given.
    Unfortunately, getopt_long() is too stupid to handle them properly, which
    means clustered options (e.g. -rRc) can no longer be used.  They must be
    separated (e.g. -r -R -c).  Also, arguments given with the short version
    must not be separated by a space (e.g. -l3).
  NOT BACKWARDS COMPATIBLE: Renamed the long command line option "use-syslog"
    to "log-level".
  Fixed middleman() to completely bypass all processing when TLS passthrough is
    active.  The additional processing was buffering TLS traffic until the data
    contained a newline character (purely by coincidence).  This buffering was
    preventing the passthrough from functioning properly.  Thanks to Dominik
    Dausch for reporting this one.

For now, DragonFly and FreeBSD use the libc version, it is not reentrant,
but thread-safe. NetBSD 3.0+ and Darwin 8.0+ use libresolv from base

Update to 2.6.3. From the changelog:

  Fixed a serious bug where spamdyke was closing the connection to qmail and
    exiting as soon as the remote host exited.  When the remote host sends its
    SMTP data in one burst and closes the connection without waiting for the
    response code from the DATA segment, qmail doesn't accept the message and
    nothing gets delivered.
  Added some code to log_writeln() to translate bare carriage returns into
    carriage return/linefeed combinations.  This allows poorly written remote
    servers to send mail, most notably Microsoft web servers.  Dogmatically
    refusing to accept mail by refusing to be more flexible than RFC 822
    will never change the world; let's be reasonable instead of bouncing
    messages back to our friends who can't change their mail servers anyway.
  Fixed smtp_filter() to accept parameters to AUTH LOGIN when the MUA sends the
    authentication information with the command instead of waiting for the
    prompts.  Thanks to Carlo Blohm for reporting this one.

Update to 2.6.2. From the changelog:

  Fixed smtp_filter() to accept parameters to AUTH PLAIN when the MUA sends the
    authentication information with the command instead of waiting for another
  Changed find_address() to strip BATV tags from addresses so whitelist/
    blacklist matching can still take place.  Reported by Walter Russo.
  Added utils/passwordcheck to help troubleshoot SMTP AUTH problems.
  Added more logging to exec_checkpassword() to aid troubleshooting.

Update to 2.6.1. From the changelog:

* Changed calls to tolower() and isalnum() to eliminate warnings
    from gcc 3.3.3 on NetBSD 3.1.  Thanks to David Frese for reporting
    this one.

* Fixed a very small typo in the new mask/flag system that was
    preventing spamdyke from advertising SMTP AUTH on unpatched
    qmail servers -- FILTER_FLAG_AUTH_ADD had the same value as
    FILTER_FLAG_AUTH_NONE.  Oops.  Thanks to Renato Franzin for
    reporting this one.

* Fixed an oversight in the use of gethostbyname() to perform DNS
    lookups for A records.  If the server is configured to search
    a domain for matching names ("search" in /etc/resolv.conf) and
    the domain has a wildcard DNS entry, the DNS RBL code was always
    matching because an A record was always found.  Adding a dot
    to the end of the queried name prevents the domain searching
    and returns correct results.  Thanks to "Paolo", Alexander
    Fordyce and Jens Mickerts for reporting and helping me troubleshoot
    this one.

Update to 2.6.0. From the changelog:

  Added support for STARTTLS, similar to the way SMTP AUTH is implemented -- if
    a server certificate is available, spamdyke takes care of the TLS.  If not
    but qmail supports TLS, spamdyke passes it through.
  Changed the read() and write() calls to the network to use macros named
    NETWORK_READ() and NETWORK_WRITE() that are replaced by TLS routines when
    TLS support has been compiled in.
  Changed the smtp_filter() return codes to use a mask/flag system because the
    possible permutations of PASS/INTERCEPT/QUIT with ADD/REMOVE/CAPTURE AUTH
    and ADD/REMOVE/CAPTURE TLS and CHILD QUIT/CONTINUE were getting too complex.
  Fixed search_file() to match a file entry where the search text matches the
    entry completely but the entry has wildcard markers at the start and/or end.
  Added TLS support to tests/sendrecv so TLS can be tested from scripts.
  Fixed numerous small bugs in tests/sendrecv that were causing inaccurate test
    results (false positives and false negatives).
  Updated all of the test scripts to make renumbering them easier.
  Added a new test script to exercise a small whitelist wildcard bug I found.
  Added 10 new test scripts to exercise the new TLS features.
  Changed process_command_line() and usage() to print a brief usage message if
    no parameters are given.
  Changed process_command_line() and usage() to print a brief error message if
    a bad parameter is given.
  Changed process_command_line() and usage() to print the full usage message if
    -h or --help is given.
  Changed process_command_line() and usage() to print the version header if -v
    or --version is given.
  Renamed test_smtpauth_crammd5, test_smtpauth_login and test_smtpauth_plain to
    smtpauth_crammd5, smtpauth_login and smtpauth_plain, respectively.
  Moved smtpauth_crammd5, smtpauth_login and smtpauth_plain from the utils
    folder to tests/smtpauth, since they're only used by the test scripts
  Added alternate command line options for people who spell "gray" with an "e".
    They do the same thing.
  Updated the documentation.

Update to 2.5.0. From the changelog:

  Moved portions of spamdyke's code from spamdyke.c into new .c and .h files to
    make it a little easier to understand and maintain.
  Added base64_encode() and base64_decode() to transfer data to/from base64
  Added md5() to produce an MD5 digest of a data block.  Turns out this wasn't
    necessary for spamdyke, only for test_smtpauth_crammd5.  Oops.
  Renamed the "make openbsd" command to "make bsd" since apparently all *BSD
    distributions don't need -lresolv.
  Renamed search_ip_file() to search_tcprules_file() and extended it to support
    IP ranges, rDNS names and remote info like tcprules does (according to  This makes the IP black/
    whitelist files much more flexible.  This will be much handier in the next
    version (AKA The Great Configuration Overhaul).
  Modified middleman() and smtp_filter(), added exec_checkpassword() so spamdyke
    can do SMTP AUTH, either by offering it itself or observing the qmail
    traffic.  LOGIN, PLAIN and CRAM-MD5 are supported.
  Changed the STRLEN_ macros in spamdyke.h to use a single STRLEN() macro so the
    preprocessor will count characters instead of doing it by hand.  Much safer
    this way.
  Removed "-a"'s (max number of recipients per message) dependence on "-d"
    (local domains file).  With SMTP AUTH, the local access file and whitelists,
    this shouldn't be necessary.
  Added process_access() to process local access files (e.g. /etc/tcp.smtp) and
    export environment variables based on the source of the incoming connection.
  Added relay prevention based on the content of the local access file(s) and
    the list(s) of local domains.  Connections from remote sources that are
    granted relay permission in the access file(s) are allowed to relay.  Users
    who authenticate with SMTP AUTH are allowed to relay.  All others must send
    to local addresses only.
  Added a series of test scripts to exercise all of spamdyke's filters and
    options.  This should make it easier to regression test new versions.
  Changed search_file() and search_tcprules_file() to compare domain names in a
    case insensitive manner.
  Changed canonicalize_path() to reduce all file paths to lowercase.  This was
    causing graylisting to be inconsistant.  Reported by

Update to 2.4.0. From the changelog:

  Added search_ip_file() to search files for IP addresses and allow wildcards,
    network sizes (numbers of bits, e.g. and netmasks (e.g.
  Added new options to allow graylisting exclusions by IP address and rDNS
  Added new options to activate graylisting for only certain IP addresses and
    rDNS names.
  Updated the documentation.

  Added some explicit casting to printf("%.*s") arguments to make them ints
    instead of longs.  gcc 3.3 on OpenBSD was complaining.
  Changed a datatype in log_write() from long to time_t.  gcc 3.3 on OpenBSD
    was complaining.
  Changed all uses of sprintf() to snprintf(), even though they were already
    safe from buffer overruns.  gcc 3.3 on OpenBSD was complaining.
  Added a new target to the Makefile in the spamdyke and utils folders named
    "openbsd" that compiles without the "-lresolv" flag.  gcc 3.3 on OpenBSD
    includes the resolver library automatically and throws an error when it
    is explicitly specified.
  Added some additional #include directives in dnsmx.c, dnsptr.c and dnstxt.c
    because they're not included by resolv.h on OpenBSD.

  Gained a broader understanding of the resolver library and DNS packet
    structure, then rewrote most of dns_txt() and dns_ptr_lookup() to (more)
    correctly process DNS data.
  Added dns_mx() to perform MX record lookups.
  Changed process_command_line() to use getopt_long() and added long option
    equivalents to the existing command line flags.
  Added the option "reject-missing-sender-mx" to reject email from senders
    whose domains aren't local and don't have MX records and/or A records.
    AOL does this.
  Updated the usage statement to show the new (long) command line options.
  Updated the README.txt to show the new (long) command line options.
  Moved domain2path and domainsplit into a new folder named "utils".
  Created dnsmx, dnsptr and dnstxt in the utils folder by copying the dns_mx(),
    dns_ptr() and dns_txt() functions from spamdyke.  They are simple command
    line utilities that no one will ever use except as examples of how to make
    MX, PTR and TXT DNS queries using libc.  As far as Google knows, there are
    no such examples anywhere else on the internet.
  Changed the DNS RBL code to check for A records in addition to TXT records.
    Some RBLs are using A records, I don't know why.
  Fixed the DNS RBL code not to check for RBL entries.

Initial import of spamdyke 2.2.1.

spamdyke monitors incoming traffic, acting as a middleman between
qmail and the remote server. It catches the sender and recipient
addresses as they go by and logs them to syslog. If it sees something
it doesn't like (e.g. a blacklisted sender), it cuts the connection,
closes qmail and fakes the rest of the SMTP transaction with the
remote server. qmail thinks the remote server disconnected normally.
The remote server thinks qmail is rejecting the message. It's the
best of both worlds.

spamdyke can optionally reject the connection if the remote server's
reverse DNS entry does not exist, does not resolve, contains its
IP address and either contains a prohibited keyword (like "dynamic")
or ends in a country code; if the IP address, reverse DNS entry,
or envelope sender is listed in a blacklist; or if data is sent
before the SMTP greeting banner is displayed. spamdyke can also
limit recipients per connection, greylist for some or all domains,
and close connections that go idle or take too long.
