  • Wide-spectrum: SpamAssassin uses a wide variety of local and network tests to identify spam signatures. This makes it harder for spammers to identify one aspect which they can craft their messages to work around.
  • Flexible: SpamAssassin encapsulates its logic in a well-designed, abstract API so it can be integrated anywhere in the email stream. The Mail::SpamAssassin classes can be used on a wide variety of email systems including procmail, sendmail, Postfix, qmail, and many others.
  • Easy Configuration: SpamAssassin requires very little configuration; you do not need to continually update it with details of your mail accounts, mailing list memberships, etc. Once classified, site and user-specific policies can then be applied against spam. Policies can be applied on both mail servers and later using the user's own mail user-agent application.


How SpamAssassin Works

SpamAssassin uses a wide range of heuristic tests on mail headers and body text to identify items as "spam",
also known as unsolicited commercial email. Once identified, the mail can then be optionally tagged as spam for
later filtering using the user's own mail user-agent application. SpamAssassin typically differentiates successfully
between spam and non-spam in between 95% and 100% of cases, depending on what kind of mail you get and your
training of its Bayesian filter. Specifically, SpamAssassin has been shown to produce around 1.5% false negatives (spam that was missed) and
around 0.05% false positives (ham incorrectly marked as spam). See the rules/STATISTICS*.txt files for more
information. SpamAssassin alsoincludes plugins to support reporting spam messages automatically or manually to
collaborative filtering databases such as Pyzor, DCC, and Vipul's Razor.
