• 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.

• see the INSTALL and UPGRADE files in the distribution.

• 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.

SpamAssassin 3.0 delivers many new features including support for sender authentication using the Sender Policy Framework (SPF), checking for web links of known spam advertisers, a modular plugin architecture, improved SQL database support for storing user data in server installations, and improved email classification.

SpamAssassin's practical multi-technique approach, modularity, and extensibility continue to give it an advantage over other anti-spamsystems. Due to these advantages, SpamAssassin is widely used in all aspects of email management. You can readily find SpamAssassin in use in both email clients and servers, on many different operating systems, filtering incoming as well as outgoing email, and implementing a very broad range of policy actions. These installations include service providers, businesses, not-for-profit and educational organizations, and end-user systems. SpamAssassin also forms the basis for numerous commercial anti-spam products available on the market today.

About SpamAssassin

These tests are applied to email headers and content to classify email using advanced statistical methods. In addition, SpamAssassin has a modular architecture that allows other technologies to be quickly wielded against spam and is designed for easy integration into virtually any email system.
