The SpamAssassin system is software for analyzing email messages, determining how likely they are to be spam and reporting its conclusions. It is a rule based system that compares different parts of email messages with a large set of rules. Each rule adds or removes points from a message's spam score. A message with a high enough score is reported to be spam."

SpamAssassin is an open source solution to spam. It is available as a standalone system, as well as being part of MPP (Message Processing Platform) from RAEInternet. It has also been included with the mail system in OSX 10.4 server (Tiger).
