FYI if this helps, Paul Graham - a member of the spamfilt forum, and one
of the people responsible for the annual Spam Conference at MIT - has
written several articles outlining the basic theory, philosophy, and
design of statistical-based filters. His website is
http://www.paulgraham.com. I think you'll find it very useful
information, with a lot of data to back up his theory.
