(Redirected from P5-Mail-SpamAssassin)
 A highly efficient mail filter for identifying spam
- SpamAssassin is a mail filter which attempts to identify spam using text analysis and several internet-based realtime blacklists.
- Using its rule base, it uses a wide range of heuristic tests on mail headers and body text to identify "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.
