*** THIS IS A RELEASE CANDIDATE ONLY, NOT THE FINAL 3.1.0 RELEASE *** SpamAssassin 3.1.0-rc2 is released! SpamAssassin 3.1.0 is a major update. SpamAssassin is a mail filter which uses advanced statistical and heuristic tests to identify spam (also known as unsolicited bulk email).
This is a release candidate, and NOT the general availability release (yet.) We think it's pretty rock solid, however. ;) Please test it out, and report any bugs to: http://bugzilla.spamassassin.org Highlights of the release ------------------------- - 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. - 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 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. - Razor: disable Razor2 support by default per our policy, since the service is not free for non-personal use. It's trivial to reenable (by editing '/etc/mail/spamassassin/v310.pre'). - 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.

Summary of changes from 3.1.0-rc1 --------------------------------- - (Many) Documentation Fixes. - Fixed problem in the PostgreSQL Bayes storage engine (bug 4531). - Syslog entries now properly identified as 'spamd' instead of 'spamassassin' (bug 4533). - Fixed situation where pyzor and dcc could be left running after a timeout (bug 4518). - Better handling of warnings while loading (bug 4536). - Spamc learning/reporting is disabled by default in spamd, can be enabled with the "--allow-tell" or "-l" option to spamd (bug 4546). - Better support IPv6 resolvers (bug 4412). - Better handle peculiarities with certain MIME boundaries (bug 4535). - Fix unitialized value warnings in spamd with TELL commands (bug 4552). - Fix sa-learn's --local option, which previously was always enabled (bug 4494). Summary of major changes since 3.0.x ------------------------------------ - 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. -- Duncan Findlay
