SpamSieve brings Bayesian spam filtering to numerous email clients, including Apple Mail, Emailer, Entourage, Eudora 5.2 or later, GyazMail, Mailsmith, Outlook Express 5, and PowerMail. SpamSieve works by analyzing the good email and spam email one has received to provide custom tailored filtering capabilities. The more SpamSieve is used, the better its filtering becomes.
