> About Apache SpamAssassin
> -------------------------
>
> Apache SpamAssassin is a mature, widely-deployed open source project
> that serves as a mail filter to identify spam. SpamAssassin uses a
> variety of mechanisms including mail header and text analysis, Bayesian
> filtering, DNS blocklists, and collaborative filtering databases. In
> addition, Apache SpamAssassin has a modular architecture that allows
> other technologies to be quickly incorporated as an addition or as a
> replacement for existing methods.
>
> Apache SpamAssassin typically runs on a server, classifies and labels
> spam before it reaches your mailbox, while allowing other components of
> a mail system to act on its results.
>
> Most of the Apache SpamAssassin is written in Perl, with heavily
> traversed code paths carefully optimized. Benefits are portability,
> robustness and facilitated maintenance. It can run on a wide variety of
> POSIX platforms.
>
> The server and the Perl library feels at home on Unix and Linux platforms
> and reportedly also works on MS Windows systems under ActivePerl.
