PeterJ Posted September 24, 2004 Share Posted September 24, 2004 In case anyone cares to check out the two recent announcements regarding the SpamAssassin 3.0 release they are pasted below. The following quote is from Daniel Quinlan and can be seen in context here: http://thread.gmane.org/gmane.mail.spam.sp...n.general/56288 Apache Software Foundation Announces SpamAssassin 3.0 Release Forest Hill, MD - September 22, 2004 -- The Apache Software Foundation is pleased to announce the release of SpamAssassin 3.0. SpamAssassin 3.0 contains a number of new technologies designed to protect against the changing techniques used by spammers. This is the first SpamAssassin release as an Apache Software Foundation project and under the Apache License. The release is available from the Apache SpamAssassin web site (http://spamassassin.apache.org/) via the Apache mirror network. 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-spam systems. 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 SpamAssassin is an intelligent email filter which uses a diverse range of tests to identify unsolicited bulk email, more commonly known as "spam". 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. About the Apache Software Foundation The Apache Software Foundation provides organizational, legal, and financial support for a broad range of open source software projects.

SURBL and SBL track sites that advertise with spam, known spam sources, and spam services. - The new 3.0 architecture allows third-parties to easily add plugin modules. - 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. Important installation notes: - The SpamAssassin 2.6x release series was the last set of releases to officially support perl versions earlier than perl 5.6.1. If you are using an earlier version of perl, you will need to upgrade before you can use the 3.0.0 version of SpamAssassin. - SpamAssassin 3.0.0 has a significantly different API (Application Program Interface) from the 2.x series of code. This means that if you use SpamAssassin through a third-party utility (milter, etc,) you need to make sure you have an updated version which supports 3.0.0. - The --auto-whitelist and -a options for "spamd" and "spamassassin" to turn on the auto-whitelist have been removed and replaced by the "use_auto_whitelist" configuration option which is also now turned on by default. - The "rewrite_subject" and "subject_tag" configuration options were deprecated and are now removed. Instead, using "rewrite_header Subject [your desired setting]". e.g. rewrite_subject 1 subject_tag ****spam(_SCORE_)**** becomes rewrite_header Subject ****spam(_SCORE_)**** - The Bayesian storage modules have been completely re-written and now include Berkeley DB (DBM) storage as well as SQL based storage (see sql/README.bayes for more information). In addition, a new format has been introduced for the bayes database that stores tokens in fixed length hashes. All DBM databases should be automatically converted to this new format the first time they are opened for write. You can manually perform the upgrade by running "sa-learn --sync" from the command line. The "sa-learn --rebuild" command has been deprecated; please use "sa-learn --sync" instead. The --rebuild option will remain temporarily for backwards compatibility. - "spamd" now has a default max-children setting of 5; no more than 5 child scanner processes will be run in parallel. Previously, there was no default limit unless you specified the "-m" switch when starting spamd. - If you are using a UNIX machine with all database files on local disks, and no sharing of those databases across NFS filesystems, you can use a more efficient, but non-NFS-safe, locking mechanism. Do this by adding the line "lock_method flock" to the /etc/mail/spamassassin/local.cf file. This is strongly recommended if you're not using NFS, as it is much faster than the NFS-safe locker. - Please note that the use of the following command line parameters for spamassassin and spamd have been deprecated and are now removed. If you currently use these flags, please remove them: in the 2.6x series: --add-from, --pipe, -F, -P, --stop-at-threshold, -S in the 3.0.x series: --auto-whitelist, -a - The following flags are deprecated and will be removed in a future major release: --whitelist-factory, -M, --warning-from, -w, --log-to-mbox, -l. - SpamAssassin runs in "taint mode" by default for improved security. Certain third-party modules, such as Razor v2, may be incompatible with taint mode. For Razor v2, you will need to be using v2.40 of razor-agents or higher which allows taint mode by default. Earlier versions which are patched to allow taint mode may be used as well. - Finally, 2.6x deprecated the use of the "check_bayes_db" scri_pt, and it is now no longer available. Please see the sa-learn man/pod documentation for more info. New rules: - SPF is supported using the Mail::SPF::Query module. - There are new rules and code to combat Bayes-poisoning text and random hash-busters; Habeas rules now check against the Habeas user list to combat forged marks used in spam. - URIDNSBL rules: these do DNSBL lookups on URLs using SURBL and SBL, allowing spamvertised URLs found in the message body to be scored. - Spamhaus XBL and a variety of new DNSBL rules were added. - Hashcash is supported. - Bob Menschel's "longwords" rules were added. - The "backhair" rules were added to combat HTML obfuscation, a technique based on Jennifer Wheeler's "backhair" ruleset. - Matt Kettler's "antidrug" rules were added. - Anti-fraud rules from Matt Yackley were added. - Some hostname-based blocklist tests based on the envelope sender address were added. - And more... Spamd changes: - spamd now uses a "preforking" model instead of "fork per message". - There is a new log format, detailing message-id, resent-message-id, tests hit, autolearn status, and other data in a format compatible with mass-check to provide more information for spamd log-summary scripts. Engine changes: - Plugins: third-party modules can now be written and loaded dynamically from inside SpamAssassin, to provide support for entirely new tests and functionality. - SQL support for Bayes and AWL storage was added, thanks to Michael Parker. See sql/README.bayes and sql/README.awl for additional information. - There was a ground-up rewrite of the MIME parser. It now deals correctly with complex MIME structures, including entire message/rfc822 message attachments. - Rules can now test the "MAIL FROM:" address used in the SMTP transaction if it was logged to the message headers using the "EnvelopeFrom" pseudo-header. This allows rules such as SPF to be applied. - Added an optional fast Bayes locking mechanism for local usage only (it's not NFS safe) using "lock_method flock". - Support for parsing mbx mailboxes (as used by UW IMAP) was added. Thanks to John Newman for this patch. - There is a refactored configuration parser to split parser code from the configuration settings. - Bayes databases can now be backed up and restored using --backup and --restore. - Config files can now include other files using the "include" command. - The GA-based evolver was replaced with a fast Perceptron score generation tool by Henry Stern; scores can now be generated much more quickly. - The "spamassassin" scri_pt can now check collections of mail en masse. This allows commands such as "spamassassin -d --mbox file1" to run over an entire mbox file. It also works for checks, adding to white/black-lists, etc. - The Windows support improved. Translations: - A Dutch translation was added, thanks to Jesse Houwing. - A French translation was added, thanks to Michel Bouissou. - A German translation was added, thanks to Klaus Heinz. - A Polish translation was added, thanks to Jerzy Szczudlowski and radek at alter dot pl. -- Daniel Quinlan ApacheCon! 13-17 November (3 SpamAssassin http://www.pathname.com/~quinlan/ http://www.apachecon.com/ sessions & more) Link to comment Share on other sites More sharing options...
