![]() The rules are called "tests" in the SpamAssassin documentation.Įach test has a score value that will be assigned to a message if it matches the test's criteria. Most rules are based on regular expressions that are matched against the body or header fields of the message, but Apache SpamAssassin also employs a number of other spam-fighting techniques. Mail filter programs such as procmail can be made to pipe all incoming mail through Apache SpamAssassin with an adjustment to a user's procmailrc file.Īpache SpamAssassin comes with a large set of rules which are applied to determine whether an email is spam or not. Typically either variant of the application is set up in a generic mail filter program, or it is called directly from a mail user agent that supports this, whenever new mail arrives.

It can be run as a standalone application or as a subprogram of another application (such as a Milter, SA-Exim, Exiscan, MailScanner, MIMEDefang, Amavis) or as a client ( spamc) that communicates with a daemon ( spamd). Methods of usage Īpache SpamAssassin is a Perl-based application ( Mail::SpamAssassin in CPAN) which is usually used to filter all incoming mail for one or several users. It was announced that development of version 4.0.0 would become project's focus. In April, 2021, version 3.4.6 of SpamAssassin was released. In December 2019, version 3.4.3 of SpamAssassin was released. The SpamAssassin 3.4.2 release in September 2019 was the first in over three years, but the developers say that "The project has picked up a new set of developers and is moving forward again.". In Summer 2004 the project became an Apache Software Foundation project and later officially renamed to Apache SpamAssassin. Mason rewrote all of Jeftovic's code from scratch and uploaded the resulting codebase to SourceForge on April 20, 2001. Apache SpamAssassin is highly configurable if used as a system-wide filter it can still be configured to support per-user preferences.Īpache SpamAssassin was created by Justin Mason, who had maintained a number of patches against an earlier program named x by Mark Jeftovic, which in turn was begun in August 1997. It can also be run by individual users on their own mailbox and integrates with several mail programs. The program can be integrated with the mail server to automatically filter all mail for a site. ![]() It is released under the Apache License 2.0 and is a part of the Apache Foundation since 2004.
