This document describes how to install SpamAssassin (for filtering
SPAM) and ClamAV (for filtering viruses, trojans, worms, etc.) and how
to invoke them by using procmail recipes. It is suitable for scenarios
where Sendmail or Postfix deliver emails to local users. It should
work (maybe with slight changes concerning paths etc.) on all *nix
operating systems. I tested it on Debian Woody so far.
