SpamAssassin in a Box

SpamAssassin in a Box is a powerful and reliable spam filter for Windows. Beside the famous e-mail filter SpamAssassin, it also contains a Windows system service, making SpamAssassin controllable via the Windows Service Control Manager. A fully preconfigured SpamAssassin is already included, as well as several enhancements (regarding stability, memory usage, signal handling, ...) for running the spam filter on a Windows system.

The service monitors SpamAssassin's daemon 'SpamD' and updates the anti-spam rules automatically. Furthermore it contains a lot of additional individual configuration options. SpamAssassin in a Box is suitable for use in Windows-based server systems, but is also supported by any other common Windows system.

SpamAssassin in a Box uses a scoring system to declare the likelihood of a mail being spam. The spam score can than be used by a continuative program, usually the MTA (Message Transfer Agent), to decide how to handle the mail. To obtain a complete anti-spam solution, you have to connect SpamAssassin in a Box to your MTA. Many well-known MTAs support a corresponding connection or can be extended by this sort of link (e.g. Microsoft Exchange or hMailServer).
