spamassassin: update to use latest rules file and install .asc file again This makes the package break later in 'make install' when it finds out that updates.spamassassin.org does not exist. Bump PKGREVISION.
update to 3.4.1: - improved automation to help combat spammers that are abusing new top level domains; - tweaks to the SPF support to block more spoofed emails; - increased character set normalization to make rules easier to develop and stop spammers from using alternate character sets to bypass tests; - continued refinement to the native IPv6 support; and - improved Bayesian classification with better debugging and attachment hashing.
Remove example rc.d scripts from PLISTs. These are now handled dynamically if INIT_SYSTEM is set to "rc.d", or ignored otherwise.
Updated to version 3.3.1. Pkgsrc changes: - Removed most of the package options; using the options framework for those choices was not quite correct in the first place. Some have now fixed values (Perl warnings and taint checks always enabled), some got converted to variables settable from the make command line, see options.mk. - pkglint complained about the variable PLIST_ADD so I renamed it to DYNAMIC_PLIST. - SpamAssassin does not come with rules anymore. As a starting point the official archive of rules at the time of the SA release is included. At installation time this set of rules gets installed through the pkgsrc INSTALL file. - Removed patch-ba and patch-bc, both were integrated upstream. - Removed patch-be. The quick fix for the bad rule was replaced by a permanent solution. Summary of major changes since 3.3.0 ==================================== bug 6335: add Spamhaus DBL as URIBL_DBL_SPAM rule Bug 6370: update ImageInfo plugin to latest release bug 6215, bug 6294: RCVD_IN_CSS rule was broken. the check_rbl_sub() syntax was incorrect, resulting in missing hits bug 6361: list 2tld and 3tld sub-domain hosters for URIBL/SURBL/DBL queries; NOTE for SARE users: This file replaces the SARE file http://www.rulesemporium.com/rules/90_2tld.cf, which will be deprecated as from 2010-05-01. Bug 6369, 6356, 6373: WIN32 support for spamd improved Bug 6267: Solaris 10 requires --syslog-socket=native bug 6304 spamd is spawning and killing processes too often - Added spamd adjustments to info level and more information for administrators + small fix to Makefile.PL Bug 6310: sa-learn --import gives Insecure dependency in open Bug 6313: -Q or -q AND -x should not result in creation of a ~/.spamassassin dir; plus: taint issues fixed Bug 6342: make test failure on if_can under perl 5.6 Bug 6340: Impossible to find user home directory of VPOPMAIL alias Bug 6072, 6343: POD warnings, documentation fixes Bug 6304 (trivial), reduce sysadmin's stress level by lowercasing the 'INTERRUPTED' in a logged message: spamd: handled cleanup of child pid [...] due to SIGCHLD: INTERRUPTED Bug 6329: POSIX::strftime in call under Win32 ActivePerl causes Perl to hang up; formatting option %e is not in a POSIX standard, use %d instead and edit Bug 6322: In DKIM ADSP eval test check_dkim_adsp() the '*' is handled incorrectly Bug 6327: Fix calling argument in utility used to determine DCC's homedir Bug 6316: DCC.pm, wrong options for dcc_proc, (plus: avoid a warning on undef in logger when dccifd socket is not provided) Bug 6287: improved DKIM plugin debugging Bug 6321 - _TOKENSUMMARY_ not working in 3.3.0 (Plugin/Bayes.pm looks-up a tag from wrong location) Bug 6312 - uninitialized value $start_time in spamd bug 5761: trivial doc fix: document SPAMD_LOCALHOST test-control env variable Summary of major changes since 3.2.5 ==================================== COMPATIBILITY WITH 3.2.5 - rules are no longer distributed with the package, but installed by sa-update - either automatically fetched from the network (preferably) or from a tar archive, which is available for downloading separately (see below, section INSTALLING RULES); - CPAN module requirements: - minimum required version of ExtUtils::MakeMaker is 6.17; - modules now required: Time::HiRes, NetAddr::IP (4.000 or later), Archive::Tar (1.23 or later), IO::Zlib; - minimal version of Mail::DKIM is 0.31 (preferred: 0.37 or later); expect some tests in t/dkim2.t to fail with versions older than 0.36_5; - no longer used: Mail::DomainKeys, Mail::SPF::Query; - either Digest::SHA or the older Digest::SHA1 is required, though note that the DKIM plugin requires Digest::SHA for sha256 hashes and Razor agents still need Digest::SHA1; - some IPv6 functionality requires IO::Socket::INET6; - if keeping the AWL database in SQL, the field awl.ip must be extended to 40 characters. The change is necessary to allow AWL to keep track of IPv6 addresses which may appear in a mail header even on non-IPv6 -enabled host. While at it, consider also adding a field 'signedby' to the SQL table 'awl' (and adding 'auto_whitelist_distinguish_signed 1' to local.cf); see sql/README.awl for details. The change need not be undone even if downgrading back to 3.2.* for some reason; - fixing a protocol implementation error regarding a PING command required bumping up the SPAMC protocol version to 1.5. Spamd retains compatibility with older spamc clients. Combining new spamc clients with pre-3.3 versions of a spamd daemon is not supported (but happens to work, except for the PING and SKIP commands); - if using one of the plugins (FreeMail, PhishTag, Reuse) which were previously not part of the official package, please retire your local copy to avoid it conflicting with a new native plugin; - as the plugin AWL is no longer loaded by default, to continue using it the following line is needed in one of the .pre files (e.g. local.pre): loadplugin Mail::SpamAssassin::Plugin::AWL - it may be worth mentioning that a rule DKIM_VERIFIED has been renamed to DKIM_VALID to match its semantics; - the DKIM plugin is now enabled by default for new installs, if the perl module Mail::DKIM is installed. However, installation of SpamAssassin will not overwrite existing .pre configuration files, so to use DKIM when upgrading from a previous release that did not use DKIM, a directive: loadplugin Mail::SpamAssassin::Plugin::DKIM will need to be uncommented in file "v312.pre", or added to some other .pre file, such as local.pre; - due to changes in some internal data structures (like Bug 6185, 6254), some third-party plugins may need to be updated. One such example is the ClamAVPlugin plugin - please find a fresh version, which can be used with both SpamAssassin versions 3.2.5 and 3.3.0, on its wiki page at http://wiki.apache.org/spamassassin/ClamAVPlugin - versions of amavisd-new between 2.5.2 and 2.6.1 (inclusive) are incompatible with SpamAssassin 3.3; please upgrade amavisd to 2.6.2 or later, or apply a workaround https://issues.apache.org/SpamAssassin/show_bug.cgi?id=6257 - support for versions of perl 5.6.* is being gradually revoked (may still work, but no promises and no support); - preferred versions of perl are 5.8.8, 5.8.9, and 5.10.1 or later; - on FreeBSD, please avoid using multithreaded versions of perl older than 5.10.0 due to small default main thread's stack size, which may not suffice for some regular expression evaluations; INSTALLING RULES Rules are normally installed by running a sa-update command. The version of sa-update program should match the version of SpamAssassin modules, so invoking sa-update should be performed only after installing or upgrading SpamAssassin code, not before. Installing rules from network is done with a single command, normally run as root: sa-update Installing rules from files: obtain all the following files: Mail-SpamAssassin-rules-xxx.tgz Mail-SpamAssassin-rules-xxx.tgz.asc Mail-SpamAssassin-rules-xxx.tgz.md5 Mail-SpamAssassin-rules-xxx.tgz.sha1 (where xxx may look something like '3.3.0.r893295') install rules from a compressed tar archive: sa-update --install Mail-SpamAssassin-rules-xxx.tgz (sa-update will need corresponding .asc and .sha1 files with the same base name in the same directory as the .tgz file) MAIN NEW FEATURES - IPv6 support was substantially improved (see below); - many improvements to the DKIM plugin (understands author domain signatures, supports multiple signatures, ADSP support with overrides) - (see below); - added 'if can(Class::method)' conditional statement, allowing configuration settings to be conditional on plugin capabilities without requiring new version releases to do so; - added a --verbose option to the sa-update utility to show updated channels; - added a configuration option 'time_limit', defaulting to 300 seconds or whatever the caller (like spamd) provides; attempting to gracefully terminate the checking when a time limit is reached, reporting the score and test hits that were collected so far, along with an added hit on a rule TIME_LIMIT_EXCEEDED; - more expensive code sections are now instrumented with timing measurements; timing report is logged as a debug message by the end of processing, and made available to a caller and to 'add_header' directives through a TIMING tag; - added a configuration option skip_uribl_checks to the URIDNSBL plugin, cross-documented it with skip_rbl_checks; - preserve order of declared 'add_header' header fields; - configurable network mask length for the AWL plugin (see below); - added support for DCC reputations (see below); - improved error handling and robustness (see below); - added timestamps when logging on stderr; - allowed debug areas to be excluded from debugging, e.g.: -D all,norules,noconfig,nodcc BUILDING AND PACKAGING - rules are no longer distributed with the package, but installed by sa-update - Makefile.PL has been simplified and a bug fixed in a DESTDIR support by increasing the minimum required version of ExtUtils::MakeMaker to 6.17 - tools check_whitelist and check_spamd are now included in the distribution, now called 'sa-awl' and 'sa-check_spamd' WORKAROUNDS TO PERL BUGS AND LIMITATIONS - modified the Check.pm plugin to produce smaller chunks of source code from rules (60 kB) to avoid Perl compiler crashing on exceeding stack size; - localized global variables $1, $2, etc at several places, avoiding taint issue from propagating; - avoided Perl I/O bug by replacing line-by-line reading with read() where suitable, or played down the EBADF status in other places and only report it as a dbg instead of a die - while also providing a little speedup (10 .. 25 %) on reading a message; - provided a new sub Message::split_into_array_of_short_lines to split a text into array of paragraph chunks of sizes between 1 kB and 2 kB, giving less opportunity to runaway regular expressions in rules; fixes bugs: 5717, 5644, 5795, 5486, 5801, 5041; MEMORY FOOTPRINT - as a side-effect of compiling rules in smaller chunks (to avoid compiler crashes), virtual memory footprint of SpamAssassin is reduced; - saved some memory by not importing the Pod::Usage unless it is needed; - saved 350k+ of memory in sa-compile by replacing DynaLoader with XSLoader; - removed unneeded index from MySQL bayes_token table; IPv6 SUPPORT - added IPv6 support for trusted_networks, internal_networks, msa_networks, whitelist_from_rcvd, and other stuff that uses NetSet and the Received header field parser, using NetAddr::IP; - allowed usage of a remote dccifd host through an INET or INET6 socket; - added IPv6 support to AWL plugin and its utility modules; a network mask length is now configurable and defaults to /48, which controls what data is stored in an AWL database; - sql/README.awl and sql/awl_*.sql: increased suggested awl.ip field width to 40 characters to be able to hold IPv6 addresses; - IP_PRIVATE now includes ipv6 variants of private address space, as well as the ipv6-mapped ipv4 addresses. - NetSet now understands that ::ffff:192.168.1.2 and 192.168.1.2 are the same address; - IPv6 addresses are now properly read from Received header fields; - when reading Received header fields, the "IPv6:" prefix is stripped from IPv6 addresses, and "::ffff:" is removed from IPv6-mapped IPv4 addresses (so strings can match them as simply IPv4 addresses); - ::1/128 is always included in the trusted_networks/internal_networks set similar to 127.0.0.0/8; - some of the IPv6 functionality in SpamAssassin requires that a perl module IO::Socket::INET6 is available (like accessing a DNS resolver over inet6, talking to a dccifd host over inet6 socket, SPAMC protocol); SPAMC - Mail::SpamAssasin::Client ping may erroneously result in broken pipe; bump spamc protocol version to 1.5, updated spamd, spamc and Client.pm; - added -n / --connect-timeout switch to spamc, allowing to separate a connection timeout from communication timeout; - added --filter-retries and --filter-retry-sleep; - increased allowed line length in spamc.conf files to 8 KiB and report an error when the limit is exceeded; - fixed issue where spamc would not time out connections to a hung spamd; - spamc client library leaked the zlib compression buffer if compression is used; - spamc long option '--dest' was broken; SPAMD - when spamd is started with the daemonize option do not exit the parent until a child signals that it has logged the pid, to allow a wrapper script to simply continue immediately after starting spamd; - additional tempfile cleanup in kill_handler; - added SPAMD_LOCALHOST option to "make test" to allow specifying non-127.0.0.1 IP address for use in FreeBSD jail; API - adding one optional argument to Mail::SpamAssassin::parse allows caller to pass additional out-of-band information to SpamAssassin (such as a deadline time, DKIM verification results, information about a SMTP session, or dynamic rule hits); this information is made available to plugins and the rest of the code through a 'suppl_attrib' hash; - added option 'master_deadline' to the suppl_attrib argument of a Mail::SpamAssassin::parse method, allowing the caller to override a time_limit configuration setting; - Plugin::Check - pick up 'rule_hits' from caller via the new mechanism and call got_hit() on them; - simplified adding dynamic score hits and dynamic rules by plugins (such as AWL, CRM114, FuzzyOcr, Check) by letting got_hit() accept options tflags and description, and letting it store a supplied dynamic score for proper reporting; - let the timing breakdown information be accessible to a caller through the existing get_tag mechanism (tag TIMING); - let the generated header fields ('add_header' configuration options) be accessible to a caller through the existing get_tag mechanism (tags ADDEDHEADER, ADDEDHEADERHAM, ADDEDHEADERSPAM); RULES - rules are no longer distributed with the package; - new scores were generated by a genetic algorithm (GA) and then manually tweaked based on cleaned datasets supplied by a dozen volunteers; - dropped redundant rules or rules causing too many false positives; - added or updated many rules; incomplete list in no particular order: vbounce, lotsa_money, muchmoney, image spam, fill_this_form, FreeMail, European Parliament, HTML attachments, uri_obfu*, urinsrhsbl, urinsrhssub, urifullnsrhsbl, URI_OBFU_X9_WS, rDNS=localhost, INVALID_DATE_TZ_ABSURD, RCVD_IN_PSBL, FRT_VALIUM*, BOUNCE_MESSAGE, VBOUNCE_MESSAGE, __BOUNCE_UNDELIVERABLE, HELO_STATIC_HOST, FILL_THIS_FORM_FRAUD_PHISH, CHALLENGE_RESPONSE, DKIM_VALID, DKIM_VALID_AU, DKIM_ADSP_*, NML_ADSP_CUSTOM_{LOW,MED,HIGH}, __VIA_ML, MIME_BASE64_TEXT, LOTTO_URI, FORGED_MUA_THEBAT_BOUN, FORGED_MUA_THEBAT_CS, UNRESOLVED_TEMPLATE, __THEBAT_MUA, __ANY_OUTLOOK_MUA, RP_MATCHES_RCVD, one-word X-Mailer, SPAN rules, skype and misquoted-HTML rules, HTML obfuscation and Google feedproxy URI rules, advance_fee updates including further evolved advance fee second-order metarules, test rule for postmaster+abuse missing, FROM_MISSPACED, fixed FROM_CONTAINS_TAB, a Facebook redirector pattern, fixed FPs with TVD_SPACE_RATIO regarding one-word emails and ISO-2022-JP, added exclusion for __ISO_2022_JP_DELIM to OBFUSCATING_COMMENT, GAPPY_SUBJECT, PLING_QUERY and FM_FRM_RN_L_BRACK rules, RATWARE_BOUNDARY plus variant, superseded all previous RATWARE_OUTLOOK stuff, resolved FP in obfuscated URI rule, fixed breakage in tbird image rule, fixed SUBJECT_FUZZY_MEDS FP on unobfuscated "meds", added misspaced From header field rule, numeric+cctld URI rule, updated FH_DATE_PAST_20XX, ... - added PSBL blacklist - http://psbl.surriel.com/ - added support for http://www.spamhaus.org/css/ - replaces HABEAS, BSP and SSC with RP CERTIFIED; - use ReturnPath's RNBL, replacing SSBL; - added rule for plain text attachments with octet-stream MIME type; - avoided false positives on ISO-2022-JP messages in several rules; - removed massmailers from uridnsbl_skip_domain in 25_uribl.cf; - updated various default whitelists, uridnsbl_skip_domain, adsp_override, ... PLUGINS - new plugins: FreeMail, PhishTag, Reuse; - now enabled by default: DKIM; - now disabled by default: AWL; - retired plugin: DomainKeys; AWL PLUGIN - plugin AWL is now disabled by default; - added new configuration options auto_whitelist_ipv4_mask_len and auto_whitelist_ipv6_mask_len to allow more control on what part of an IP address is stored into an AWL database; - README.awl: increased a suggested awl.ip field width to 40 characters to support IPv6 addresses; - AutoWhitelist.pm: allowed storing a canonicalized IPv6 address, cropped to a configurable network mask (previously causing SQL server errors: 'value too long'); - let AWL with SQL keep separate records for DKIM-signed and unsigned mail (when auto_whitelist_distinguish_signed configuration option is true, and a field awl.signedby exists); - avoided a race condition in SQLBasedAddrList.pm when multiple processes try to insert-or-update an awl SQL record: trying INSERT first, and if that fails go for UPDATE; - gracefully handle NaN from corrupted database or a broken emulator or virtualizer; DCC PLUGIN - added support for DCC reputations, added setting dcc_rep_percent, new test check_dcc_reputation_range(), new tag DCCREP (DCC servers supply reputation data only to licensed clients); - allowed usage of a remote dccifd host through an INET or INET6 socket; DKIM PLUGIN - the DKIM plugin is now enabled by default for new installs if the perl module Mail::DKIM is installed. However, installing SpamAssassin will not overwrite existing .pre configuration files, so to use DKIM when upgrading from a previous release that did not use DKIM, the directive: loadplugin Mail::SpamAssassin::Plugin::DKIM will need to be uncommented in file "v312.pre", or added to some other .pre file, such as local.pre; - absolute minimal version of Mail::DKIM is 0.31; support for ADSP requires Mail::DKIM 0.34; a DNS test (and rule) for NXDOMAIN is operational since Mail::DKIM 0.36_5, so effectively the recommended version is Mail::DKIM 0.37 or later; - a perl module Digest::SHA is required if the DKIM plugin is enabled. If a perl module Digest::SHA is available, the module Digest::SHA1 becomes optional as far as SpamAssassin is concerned, but is still needed by Razor agents; - added support for multiple signatures (useful for whitelisting); - plugin now distinguishes author domain signatures from third party signatures (useful for whitelisting); - provides a tag DKIMIDENTITY (in addition to DKIMDOMAIN); - DKIM now supports Author Domain Signing Practices - ADSP (RFC 5617); - use the Mail::DKIM::AuthorDomainPolicy instead of Mail::DKIM::DkimPolicy, when available (since Mail::DKIM 0.34); - implements an 'adsp_override' configuration directive and adds an eval:check_dkim_adsp check, which is used by new DKIM_ADSP_* rules; - rules contain an initial set of 'adsp_override' directives, listing some of the more popular target domains for phishing (applicable only to domains which sign all their direct mail with a DKIM or DK signature); - this plugin can now re-use Mail::DKIM verification results if made available by a caller, which saves resources and makes it possible for SpamAssassin to work on a truncated large mail without breaking DKIM signatures; - check_dkim_signed and check_dkim_adsp eval rules can now take an optional list of domain names, which limits their action to listed domains only. It facilitates building DKIM-based rules for specific domains, without having to resort to meta rules; - draft-ietf-dkim-ssp-10/RFC-5617 made Author Domain Signature based on 'd': updated ADSP code accordingly; changed whitelisting code to be based on SDID ('d') instead of AUID ('i'); - Plugin/DKIM.pm: terminology changes in comments and logging according to RFC 5617 and draft-ietf-dkim-rfc4871-errata-07; BUG FIXES - fixed Rule2XSBody segfaults; - no longer treat user data as perl booleans (a string "0" is a false); - avoid data from the wild be interpreted as perl regular expressions; - ArchiveIterator: prevent _scan_directory from passing directories to _scan_file (on NFS it would fail with EISDIR on read(2); - fixed inserting the SpamAssassin -generated header fields after a multiline Return-Path header field; - fixed vpopmail support; - fixed incorrect mode bits when creating lock files for AWL; - fixed some cases where :addr headers were parsed incorrectly; - fixed leakage of 'whitelist_from_rcvd' entries between spamd users; - fixing run_and_catch, which failed to catch a non-timed run; - 127/8 isn't an illegal IP; - reworked the M::S::Timeout module to deal with nested timers as one would expect: an inner timer shouldn't be able to extend an outer timer's limit; account for time elapsed in the submitted subroutine when restarting an outer timer; reset() should have accounted for time already spent; deal with nested timed runs where alarm(0) does not provide remaining time; - the 'exists:' evaluator in HEADER rules now works as documented and tests for existence of a header field, instead of testing for a header field body being nonempty; internally, the pms->get can also now distinguish between empty and nonexistent header fields; - applied fixes to header fields parsing in several places: header field names are case-insensitive, whitespace is not required after a colon, obsolete rfc822 syntax allowed whitespace before a colon; VBounce: match "Received:" only at the beginning of a line; - fixed bugs 6237 and 6295: 1.0.0.0/8 and 2.0.0.0/8 are now valid allocated address ranges, fixed a corresponding rule RCVD_ILLEGAL_IP; - fixed bug 6205 comment 5 in URIDetail.pm; - 'pyzor_options' in Plugin/Pyzor.pm was not untainted; - made the URIDetail plugin taint safe; - fixed parsing of multi-line Received header fields for BOUNCE_MESSAGE/VBOUNCE_MESSAGE et al; - Bug 6206, Bug 2536: spamd: untaint directory as obtained from a password file or from vpopmail utilities, avoid implicit untainting; report error if user preferences file exists but cannot be accessed; - avoided using raw data from DNS as a regexp in Plugin/ASN.pm; - ensured the dbg() and info() calls always return the same value (true) regardless of log level; - suppressed logging of $& when its value is not available (i.e. when no regexp has been evaluated during rule evaluation); - Exporter never really worked in SA, was not enclosed in BEGIN {}; - masses/runGA and masses/mk-baseline-results: prevent a shell 'source' command from loading an unrelated file named 'config' which happens to be in the current PATH - must use a ./ in an arg to a 'source' command; ERROR HANDLING, ROBUSTNESS - improved error detection and reporting: test status of all system calls and I/O operations (or explicitly document where not), and report unexpected failures; - eval calls now check for eval result instead of testing the $@, which is not always reliable; - localized $@ and $! in DESTROY methods to prevent potential calls to eval and calls to system routines in code executed from a DESTROY method from clobbering global variables $@ and $!; - Util::helper_app_pipe_open_unix: contain a failing exec with an eval to prevent additional cases of process cloning. The exec could fail this way when given tainted arguments; - Util::helper_app_pipe_open_unix: flush stdout and stderr before forking, otherwise an error reported by exec (such as 'insecure dependency') was lost in a buffer; - eval-protected an open($fh,'-|') to capture implied fork failures due to lack of system resource; - explicit untainting: combine "use re 'taint'" with untaint_var(), avoiding implicit perl untainting, along with workarounds to prevent it; - added 'use strict' where missing; - avoided a bunch of warnings on "Use of uninitialized value"; - clearly report reasons for helper application process failures; - t/SATest.pm: provide information about the process failure reason if a system() call fails; improved its reporting of failures; - improved error reporting in Plugin/DCC.pm on finding a DCC home directory to facilitate troubleshooting; OTHER CHANGES - pseudoheader "ALL:raw" returns a pristine header section, and pseudoheader "ALL" returns a cleaned header section - total rewrite of URI detection in plain text body; - many updates to the list of top level domains; - added 'util_rb_3tld', allowing 3-level TLDs to be listed in URIBLs and allowing new 3TLDs to be added from rule updates; - avoided trusted_networks bog down due to O(n^2) loop with millions of entries; - applied fixes to Plugin/VBounce.pm, updated VBounce ruleset; - added support for a 'Communigate Pro' Received header field; - parse Communigate Pro "with HTTPU" auth token; - let DependencyInfo.pm understand a concept of recommended module version, besides a required version; - provided a workaround for Net::DNS::Packet::new inconsistency; - let SpamAssassin use either Digest::SHA or Digest::SHA1, whichever is available (the Digest::SHA is now a base module since perl 5.10.0); - improved parsing of eval-type rules: allow unquoted domain names as arguments, disallow unmatched quotes; - provided a new module Mail::SpamAssassin::BayesStore::BDB. It should be treated as alpha-quality (needs more testing) and is not yet ready for production use; - exposed existing function 'received_within_months' as an eval function in Plugin/HeaderEval.pm; - moved rc script to /var/lock/subsys/spamd instead of /var/lock/subsys/spamassassin so 'service spamd status' will work; - added feature to re-download MIRRRORED.BY files at least once a week, or if 'sa-update --refreshmirrors' switch is used; - input delimiter $/ can be corrupted by a plugin, localize $/ and $\ before calling a plugin; - bumped the retry counter to 180 seconds for starting spamd on slow machines; - resolved Bug 5325: syslog severity level in spamc/libspamc.c for max message size (changed LOG_ERR into LOG_NOTICE for the message: "skipped message, greater than max message size"); - added checker to avoid taint warnings if hostname is returned as '(none)'; - altered sa-update to produce an error message if a channel doesn't exist; - Bug 6150, Bug 6127, Bug 5981, Bug 5950, Bug 6191: let spamd log/report a child process exit status or aborting condition in an informative way; - added checker to detect accidental match-everything regexps in rules; - updated garescorer for 3.3.0: use more epochs in GA runs for better scores; clarify some mass-check warning output, ensure rule name always appears at start of line; if a rule had no default/existing score in 50_scores.cf, don't tell the GA that 1.0 is an appropriate default value, instead pick the midway point of its score range. this produces better results; remove some dead code from masses/score-ranges-from-freqs; - set garescorer.c to report performance as iterations per second; - added test to ensure that all config settings are correctly handled when switching between users; added more config setting type metadata to enable those tests to work; and fix URIDetail to store config on the {conf} object, not on the plugin; - moved 'release tests' to xt/ directory; mirror long-running, net-tests and stress tests with xt/50_testname.t scripts to enforce their run before a release; - made numerous additional and updated self-tests; - added a Test::Perl::Critic release-test; - cleaned up some code based on suggestions by perl module Test::Perl::Critic, among others: . enable TestingAndDebugging::ProhibitNoStrict test but allow the use of 'no strict "refs"'; . deal with BuiltinFunctions::RequireGlobFunction; . deal with ControlStructures::ProhibitMutatingListFunctions removing this exception from xt/60_perlcritic.t; . deal with BayesStore/BDB.pm, Variables::ProhibitConditionalDeclarations . now that the module Time::HiRes is a required module, we can afford to replace a select() with Time::HiRes::sleep, and remove exception BuiltinFunctions::ProhibitSleepViaSelect from xt/60_perlcritic.t; - updated documentation, fixing numerous typos and mistakes in documentation text and in log messages; - extensively improved development process: . automated testing through Hudson, a continuous integration tool; . improved mass-check system and rules oversight;
Updated to version 3.2.0. Pkgsrc changes: - Removed PKG_DESTDIR_SUPPORT until the issue with encoded ownership in +INSTALL files is resolved. - made pkglint shut up about some warnings (CONFIGURE_DIRS, BUILD_DIRS, hidden commands with @) - parse-rules-for-masses has moved in the source archive. - The directories "masses" and "tools" are no longer distributed in the archive so I simplified the post-install target. - Since "tools" is gone, the post-extract: target is obsolete. - MESSAGE now points at sa-compile. - Spamc depends on zlib now, so we needed the appropriate buildlink3 file. Summary of changes since version 3.1.8: ======================================= * new behavior for trusted_networks/internal_networks: the 127.* network is now always considered trusted and internal, regardless of configuration. * bug 3109: short-circuiting of 'definite ham' or 'definite spam' messages based on individual short-circuit rules using the 'shortcircuit' setting, by Dallas Engelken <dallase /at/ uribl.com>. * bug 5305: implement 'msa_networks', for ISPs to specify their Mail Submission Agents, and extend network trust accordingly. * bug 4636: Add support for charset normalization, so rules can be written in UTF-8 to match text in other charsets. * sa-compile: compilation of SpamAssassin rules into a fast parallel-matching DFA, implemented in native code. * "tflags multiple": allow writing of rules that count multiple hits in a single message. * bug 4363: if a message uses CRLF for line endings, we should use it as well, otherwise stay with LF as usual; important for Windows users. * bug 4515: content preview was omitting first paragraph when no Subject: header was present. * The third-party modules used by sa-update are now required by the SpamAssassin package, instead of being optional. * Bug 5165: 'sa-update --checkonly' added to check for updates without applying them; thanks to <anomie /at/ users.sourceforge.net> * Bugs 4606, 4609: Adjust MIME parsing limits for nested multipart/* and message/rfc822 MIME parts. * bug 5295: add 'whitelist_auth', to whitelist addresses that send mail using sender-authorization systems like SPF, Domain Keys, and DKIM * Removed dependency on Text::Wrap CPAN module. * Received header parsing updates/fixes/additions. Spamc / spamd: * bug 4603: Mail::SpamAssassin::Spamd::Apache2 -- mod_perl2 module, implementing spamd as a mod_perl module, contributed as a Google Summer of Code project by Radoslaw Zielinski. * bug 3991: spamd can now listen on UNIX domain, TCP, and SSL sockets simultaneously. Command-line semantics extended slightly, although fully backwards compatibly; add the --ssl-port switch to allow TCP and SSL listening at the same time. * bug 3466: do Bayes expiration, if required, after results have been passed back to the client from spamd; this helps avoid client timeouts. * more complete IPv6 support. * spamc: Add '-K' switch, to ping spamd. * spamc: add '-z' switch, which compresses mails to be scanned using zlib compression; very useful for long-distance use of spamc over the internet. * bug 5296: spamc '--headers' switch, which scans messages and transmits back just rewritten headers. This is more bandwidth-efficient than the normal mode of scanning, but only works for 'report_safe 0'. * Bump spamd's protocol version to 1.4, to reflect new HEADERS verb used for '--headers'. Mail::SpamAssassin modules and API: * bug 4589: allow M::SA::Message to use IO::File objects to read in message (same as GLOB). * bug 4517: rule instrumentation plugin hooks, to measure performance, from John Gardiner Myers <jgmyers /at/ proofpoint.com>. * add two features to core rule-parsing code; 1. optional behaviour to recurse through subdirs looking for .cf/.pre's, to support rules compilers working on rulesrc dir. 2. call back into invoking code on lint failure, so rule compiler can detect which rules exactly fail the lint check. * bug 5206: detect duplicate rules, and silently merge them internally for greater efficiency. * bug 5243: add Plugin::register_method_priority() API, allowing plugins to control the relative ordering of plugin callbacks relative to other plugins' implementations. * Reduced memory footprint. Plugins: * bug 5236: Support Mail::SPF replacement for Mail::SPF::Query. * bug 5127: allow mimeheader :raw rules to match newlines and folded-header whitespace in MIME header strings. * bug 4770: add ASN.pm plugin, contributed by Matthias Leisi <matthias at leisi.net> * bug 5271: move ImageInfo ruleset into 3.2.0 core rules, thanks to Dallas Engelken <dallase /at/ uribl.com>. * VBounce ruleset and plugin: detect spurious bounce messages sent by broken mail systems in response to spam or viruses. (Based on Tim Jackson's "bogus-virus-warnings.cf" ruleset.) * DomainKeys/DKIM: Mail::DKIM is now preferred over Mail::DomainKeys, since the latter module is no longer actively maintained, and Mail::DKIM can handle both DomainKeys and DKIM signatures. * DKIM: separate signature verification from fetching a policy: can save a DNS lookup for each unverified message by setting score to 0 for all policy-related rules (DKIM_POLICY_SIGNALL, DKIM_POLICY_SIGNSOME, and DKIM_POLICY_TESTING). (thanks to Mark Martinec) * DKIM: support testing flags in the public key, as well as in the policy record. (thanks to Mark Martinec) * DKIM: skip fetching a policy (SSP) if a signature does verify, according to draft-allman-dkim-ssp-02 (thanks to Mark Martinec) * Move rule functionality and checking into separate Check plugin, allowing third parties to implement alternative scanner core algorithms. * core EvalTests code moved into various plugins. * Plus lots of miscellaneous bug fixes.

Updated to version 3.1.1. Pkgsrc changes: - Generic option "online-tests" replaces "spamassassin-test-net". - Removed underscore from package-internal variables (pkglint complained). - patch-ay disables the SPF plugin to avoid confusing warnings in the log files. - patch-az fixes http://issues.apache.org/SpamAssassin/show_bug.cgi?id=4826. Relevant changes since version 3.1.0: ===================================== - better validate a number of different configuration options - support new Mail::DomainKeys API, which changed incompatibly between 0.18 and 0.80 without warning - more properly handle new Received header formats - bug 4788: backport sa-update from 3.2 along with the local_state_dir code, etc. - bug 4760: strictly validate trusted/internal network configurations - bug 4696: consolidated fixes for timeout bugs - bug 3710: add timeout to connect so spamc -t works - bug 4363: if a message uses CRLF for line endings, use it for header rewrites as well - bug 4748: add ExpressionEngine and Google redirector patterns - bug 3815: add _RELAYCOUNTRY_ tag so that the RelayCountry plugin can put in the list of countries relayed through - bug 4090: x86_64 platforms (linux specifically) have an issue compiling libspamc.so causing RPM build failures - bug 4791: fix issue where perl would throw a UTF-8 warning for certain messages - bugs 4606, 4609: Adjust MIME parsing limits - bug 4780: fix IP_ADDRESS & LOCALHOST regexes to correctly parse IPv6 addresses - bug 4728: DUL rules should only use the last external IP, not all but the first of the external IPs - bug 4700: certain privileged configuration settings can inject code, due to a bad fix for bug 3846. Back that out
Updated to version 3.1.0. Pkgsrc changes: - p5-Storable is no longer a necessary. - Let DragonFlyBSD also use the rc.d script (patch-ad). - Sa-update needs p5-libwww (for LWP::UserAgent, HTTP::Date), p5-Archive-Tar and p5-IO-Zlib. - Many of the plugins are available as pkgsrc packages (p5-Mail-SPF-Query, p5-IP-Country, p5-Net-Ident, ...) but are not required. - Renamed some options to follow the naming conventions described in the pkgsrc guide. - Removed patch-ax again; it is already incorporated in 3.1.0. - Reworked DESCR to use less than 25 lines. - Removed SPAMASSASSIN_VERSION for clarity of DISTNAME and PKGNAME. - Prepended variables internal to the package with an underscore. - Rearranged MAKE_PARAMS alphabetically. - Simplified some internal variables (concatenation instead of substitution: _EGDIR, _DOCDIR,...) - Loop variables use all lower-case now. - Added a rule to lower score for mail from pkgsrc-bugs in netbsd_lists.cf. - The test t/spf.t (fails for SPF_HELO_*) has a know problem (SA Bug 4685). Relevant changes since version 3.0.4: ===================================== - Apache preforking algorithm adopted; number of spamd child processes is now scaled, according to demand. This provides better VM behaviour when not under peak load. - Inclusion of sa-update script which will allow for updates of rules and scores in between code releases. - added PostgreSQL, MySQL 4.1+, and local SDBM file Bayes storage modules. SQL storage is now recommended for Bayes, instead of DB_File. NDBM_File support has been dropped due to a major bug in that module. - detect legitimate SMTP AUTH submission, to avoid false positives on Dynablock-style rules. - new Advance Fee Fraud (419 scam) rules. - removed use of the Storable module, due to several reported hangs on SMP Linux machines. - Converted several rule/engine components into Plugins such as: AccessDB, AWL, Pyzor, Razor2, DCC, Bayes AutoLearn Determination, etc. - new plugins: DomainKeys (off by default), MIMEHeader: a new plugin to perform tests against header in internal MIME structure, ReplaceTags: plugin by Felix Bauer to support fuzzy text matching, WhiteListSubject: plugin added to support user whitelists by Subject header. - TextCat language guesser moved to a plugin. (This means "ok_languages" is no longer part of the core engine by default.) - Razor: disable Razor2 support by default per our policy, since the service is not free for non-personal use. It's trivial to reenable. - DCC: disable DCC for similar reasons, due to new license terms. - Net::DNS bug: high load caused answer packets to be mixed up and delivered as answers to the wrong request, causing false positives. worked around. - DNSBL lookups and other DNS operations are now more efficient, by using a custom single-socket event-based model instead of Net::DNS. - add support for accreditation services, including Habeas v2. - better URI parsing -- many evasion tricks now caught. - URIBL lookups are prioritized based on the location in the message the URI was found. - mass-check now supports reusing realtime DNSBL hit results, and sample-based Bayes autolearning emulation, to reduce complexity. - sa-learn, spamassassin and mass-check now have optional progress bars. - modify header ordering for DomainKeys compatibility, by placing markup headers at the top of the message instead at the bottom of the list. - spamd/spamc now support remote Bayes training, and reporting spam. - spamc now supports reading its flags from a configuration file using the -F switch, contributed by John Madden. - added SPF-based whitelisting. - Polish rules contributed by Radoslaw Stachowiak. - many rule changes and additions.
RCD_SCRIPTS_EXAMPLEDIR is no longer customizable. And always is defined as share/examples/rc.d which was the default before. This rc.d scripts are not automatically added to PLISTs now also. So add to each corresponding PLIST as required. This was discussed on tech-pkg in late January and late April. Todo: remove the RCD_SCRIPTS_EXAMPLEDIR uses in MESSAGES and elsewhere and remove the RCD_SCRIPTS_EXAMPLEDIR itself.
Update to version 3.0.0. Tested on NetBSD 1.6.2, Solaris 9 and Debian 3.0. Important changes since 2.64 (for details see the file 'Changes') - support for sender authentication using the Sender Policy Framework (SPF) - checking for web links of known spam advertisers (SURBL) - modular plugin architecture - improved SQL database support for storing user data in server installations - improved email classification - SpamAssassin is now part of the Apache Foundation
mk/bsd.pkg.install.mk now automatically registers the RCD_SCRIPTS rc.d script(s) to the PLIST. This GENERATE_PLIST idea is part of Greg A. Woods' PR #22954. This helps when the RC_SCRIPTS are installed to a different ${RCD_SCRIPTS_EXAMPLEDIR}. (Later, the default RCD_SCRIPTS_EXAMPLEDIR will be changed to be more clear that they are the examples.) These patches also remove the etc/rc.d/ scripts from PLISTs (of packages that use RCD_SCRIPTS). (This also removes now unused references from openssh* makefiles. Note that qmail package has not been changed yet.) I have been doing automatic PLIST registration for RC_SCRIPTS for over a year. Not all of these packages have been tested, but many have been tested and used. Somethings maybe to do: - a few packages still manually install the rc.d scripts to hard-coded etc/rc.d. These need to be fixed. - maybe remove from mk/${OPSYS}.pkg.dist mtree specifications too.
Update to 2.63. Tested on NetBSD and Solaris 8. Summary of major changes since 2.62 ----------------------------------- - Fixed bug related to perl 5.005 which stopped SpamAssassin from being runnable - Fixed bug where "spamassassin -l" parameter wouldn't be untainted before being used - Added caching of body rendering results so that the message wouldn't be rendered the same way multiple times unnecessarily. Summary of major changes since 2.61 ----------------------------------- - Fixed two bugs related to Received line generation and parsing. - Modified two rules to reduce false positives. - Fixed bug where spamd temporary init directory wasn't removed in some situations. - Modified HABEAS_SWE to function even if the Habeas headers were out of their normal order. - Fixed bug where reporting wouldn't remove message markup before being learned by Bayes. - Fixed bug where report_safe_copy_headers would reverse the order of the Received headers. - Fixed several bugs in the Bayes system caused by DB_File oddities.
Update to version 2.61 Summary of major changes since 2.60 ----------------------------------- - Dramatically reduced memory usage of Bayes expiry. - avoid false positives on Outlook 2003 messages, mails from Mac, Palm, and localized versions of Eudora, several AOL MUAs, and newer versions of The Bat! - new set of French translations from Michel Bouissou - updated to reflect new Dynablock DNSBL location - avoids a possible hole that was giving AWL bonuses to spammer forgeries on some networks - miscellaneous bug fixes
Update to version 2.60 (fixes PR pkg/23318): Summary of changes since 2.5x ----------------------------------- - spamd supports UNIX-domain sockets - SSL support for spamc/spamd now usable - improved Bayes text analysis - improved expiration of Bayes-DB - better detection of 'invisible text' and other obfuscation techniques in HTML - new RBL (eg SORBS, SpamCop, Osirusoft dropped) - better handling of RBL timeouts - support for Razor V1 dropped - more flexible header and report rewriting - Perl taint mode enabled by default - bug fixes - new rules
Update to version 2.53. This also closes PR pkg/21114 (thanks to Todd Vierling for dynamic PLIST) Most serious bugs since release of SA 2.50 fixed (hence the 'long' delay for the Pkgsrc package). Dependence on procmail removed. You still need a mail delivery agent but procmail is only a recommendation, not a prerequisite. Runs on Solaris (somewhat tested on Solaris 8, feedback welcome). Includes some SSL support for spamc/spamd. Not yet recommended due to lurking bug(s) (SA bugzilla ID 1751). Uses Perl module DB_File now instead of NDBM_File. This changes the name and format of the auto-whitelist database ('auto-whitelist' instead of 'auto-whitelist.db' on NetBSD). ! This release adds/changes/removes configuration options, PLEASE use ! ! 'perldoc Mail::SpamAssassin::Conf' and make sure your mail ! ! configuration still works as expected. ! ========================================================================== Changes since 2.52: - corruption of Bayes db where nspam/nham was getting zeroed, fixed. - Bayes now has much lower lock timeouts for opportunistic expiry and auto-learning, to avoid overloading busy servers with an expiry run. (This may result in occasional "lock failed" messages in the syslog while you're doing manual sa-learn ops, but those are not serious; it just means that an auto-learn could not take place because the dbs were opened by you in another process.) - NDBM_File does not provide an EXISTS method, worked around. - BSMTP support (spamc -B) fixed. - Bayes allowed the user to 'forget' messages they hadn't learned. - sa-learn broken when installed in a non-standard location. - spamc was failing to dump message if out of memory. - add-all-addrs-to-blacklist was a no-op, fixed. - syslog-socket support was broken, fixed. - sslspamc compilation fixed. - SIGCHLD handling in spamd was causing an ugly warning on Red Hat 8. - user_prefs were left world-writable after auto-whitelist use. - Razor was zeroing %ENV; protected against this. - some test failures on 5.005 and with Razor fixed; some tests were also still using the user's Bayes dbs. - Windows portability fix in new Bayes journal code. - dialup_codes now a privileged setting. - clean PATH env variable immediately upon spamd start; fixed problem with taint mode failures when getting hostname in Perl 5.005. - NetBSD: fixed SSL support, spamd start script. - single-Received-header mails were not getting DNSBL checks. - some doco fixes. Changes since 2.51: - bug 1664: expiry imposed way too much load when a single site-wide Bayes db was used, fixed - bug 1672: a typo in a backported patch for 2.51 caused Bayes to sometimes not unlock the db, fixed - INSTALL now strongly recommends using DB_File - some NetBSD support fixes - bug 1601: option --syslog-socket wasn't implemented - bug 1260: corrected description of --nocreate-prefs option Changes since 2.50: - Bayes locking and concurrency issues fixed - Bayes expiration was not working; fixed - spamd was not enabling Bayes after auto-learning without restart; fixed - safer way to attach spams, for broken mail clients, using 'report_safe 2' - a few doco cleanups Main changes since 2.4x: - Bayesian filtering, using a Bayesian-style form of probability-analysis classification. This uses an algorithm based on the one detailed in Paul Graham's 'A Plan For Spam' paper, along with aspects taken from Graham Robinson's work, and the chi-combining technique developed by the SpamBayes project. - Auto-learning. This trains the Bayesian filter automatically, based on the results from traditional SpamAssassin diagnosis. It uses a set of heuristics and separate thresholds to ensure (as much as is possible) that it trains on guaranteed non-spam and spam. Old, unused tokens are automatically expired. - much-improved rule set. A whole new set of rules based on Message-Id analysis is now in place, which accurately detects forged headers from a wide range of spamware. Many inaccurate rules have been dropped. HTML tests much improved, with a set to detect image-only spam. - new default format for detected-spam messages; the message is encapsulated as a MIME part, with a preview and the spam report in the main part of the message. - Score sets. Based on whether you are using just SpamAssassin rules, adding network tests, and using a trained Bayesian database, SpamAssassin will use a set of scores appropriately to gain the maximum degree of accuracy. - Italian, Polish, Spanish, French and German rule sets and translations. - Much improved reliability with spamd. The problems with signals have been cleared up thanks to a pipe-based child tracking system, and all spamd-hanging bugs reported have proved unreproducable. - Unicode problems with Red Hat 8 and perl 5.8 fixed. Works on Perl 5.005, 5.6.x, and 5.8.x. - Taint-safe. SpamAssassin runs with perl's taint-checking enabled for better security. - Razor 1 support is now officially deprecated. - "spamc -c" was not working, fixed. This fix required increasing the revision of the spamd protocol; only difference is that now more than one protocol header can appear in the reply from spamd. - all fixes from 2.44 included.
Update to 2.43 Item 1) was already provided by 'inofficial' patch-af for 2.42 (now removed). Two new patches (-ag and -ah) from the SpamAssassin-current repository work around a roblem with razor2 timeouts. Logo 'ninjabutton.png' is now in the correct html directory. Official changes: 1) AWL change reverted; instead of decreasing the AWL bias gradually to allow frequently-seen addresses to get into the "nonspam" area, it now behaves like 2.31 did, in that the AWL simply represents the long-term average score from that correspondent. 2) core-dump bug in spamd worked around, _except for the "-m" switch_. The "-m" switch relies on signal handling in the Perl interpreter, which seems to have some bugs we cannot work around reliably on some platforms, so its use is no longer recommended. 3) some portability fixes for SunOS.
- Setting PKG_SYSCONFBASE in /etc/mk.conf works now (Thanks to Urban Boquist). - Included fix for bad AWL behaviour which will also be in 2.50 (maybe 2.43) (ie AWL works the same again as in SA 2.31). This causes revision bump.
Update to 2.42. Uses buildlink2 and module.mk. Some perl scripts for rule developers (in PREFIX/share/doc/spamassassin/{masses,tools}/) and a small SpamAssassin logo (PREFIX/share/doc/spamassassin/html/) are now included. New netbsd_lists.cf file to reduce false positives on NetBSD lists (so far, only some rules for netbsd-bugs). Changes: - bug fixes - new, better scores (intensive testing was done to improve on 2.40 and 2.41) - netbsd rc.d script works now with NetBSD 1.5 and 1.6 - management of addresses in the automatic whitlist now easier with dedicated options (--add-addr-to-whitelist, --remove-addr-from-whitelist)
Update spamassassin to 2.41. Major changes include: - SpamAssassin now *REQUIRES* procmail for local delivery support; "-P" option is now the default. Unless you use procmail, Mail::Audit, KMail, or an MTA-level integration, do not upgrade blindly, your mail *WILL* spill all over the floor in a big mess. - significant speed increases, mostly from Matt Sergeant and Dan Quinlan - bugs in whitelist_to, all_spam_to and friends fixed - rules which were causing too many false-positives removed or fixed: DOUBLE_CAPSWORD, UPPERCASE_25_50, PARTIAL_RFC_2369, MSGID_CHARS_SPAM, many others - lots of rule fixes, and lots of new rules
Updated spamassassin to 2.31nb1 Add rc.d/spamd (From norm at sandbox org uk)
Rename pkgsrc/mail/p5-Mail-Spamassassin to pkgsrc/mail/spamassassin.
Rename pkgsrc/mail/p5-Mail-Spamassassin to pkgsrc/mail/spamassassin.
Rename pkgsrc/mail/p5-Mail-Spamassassin to pkgsrc/mail/spamassassin.
spamassassin is already present as p5-Mail-SpamAssassin (how obvious... NOT!)
Add spamassassin-2.31: Spam identifier and blocker SpamAssassin is a mail filter which attempts to identify spam using text analysis and several internet-based realtime blacklists. Using its rule base, it uses a wide range of heuristic tests on mail headers and body text to identify "spam", also known as unsolicited commercial email. Once identified, the mail can then be optionally tagged as spam for later filtering using the user's own mail user-agent application. In its most recent test, SpamAssassin differentiated between spam and non-spam mail correctly in 99.94% of cases. Since then, it's just been getting better and better!
