SpamAssassin for Windows

SpamAssassin for Windows is a powerful e-mail filter which attempts to identify spam using a variety of mechanisms including text analysis, Bayesian filtering, DNS blocklists, and collaborative filtering databases.

SpamAssassin is a project of the Apache Software Foundation (ASF) and was adapted for Windows by JAM Software. In combination with an MTA (Mail Transport Agent), e.g. Hamster or MS Exchange, it is a very effective anti-spam solution. The freeware contains, beside several modules, the following SpamAssassin components as executable files for Windows (.exe):

• spamassassin.exe (mail filter)
• spamd.exe (SpamAssassin as a server process (daemon))
• WinSpamC.exe (client for spamd)
• sa-update.exe (SpamAssassin rule updates)
• sa-learn.exe (trains Bayes filter with spam/ham mail)

Please note: SpamAssassin for Windows is not a mail router and should be watched by a service when used in a productive server. For professional use or if you need additional functionality, try SmartPOP2Exchange or Exchange Server Toolbox. Both include SpamAssassin which is already preconfigured in the installation.
