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 Advance Fee Fraud (419 scam) rules. + +- removed use of the Storable module, due to several reported hangs on SMP + Linux machines. + +- 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. + +- AccessDB, Pyzor: moved to their own plugins to trim down the core engine. + +- 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. + +- 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 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. - - SpamAssassin now includes support for SPF (the Sender Policy Framework, - http://spf.pobox.com/). +- added SPF-based whitelisting. - - Web site links contained in the message are checked against SURBL and - SBL. SURBL and SBL track sites that advertise with spam, known spam - sources, and spam services. +- Polish rules contributed by Radoslaw Stachowiak. - - The new 3.0 architecture allows third-parties to easily add plugin modules. +- many rule changes and additions. - - There is now SQL database support for both the Bayes and auto-whitelist - modules, allowing more large sites to easily deploy SpamAssassin. - - A more accurate simulation of email client handling of MIME and HTML - improves our accuracy. In addition, there is better detection and - handling of spammer techniques that try to trick anti-spam software. Downloading -----------
