I have been wrestling with this of late and stumbled upon this article in the Linux Gazette (http://linuxgazette.net/105/youngman.html).

The overview is excellent and can help in identifying methods for further battling the ever increasing volume of spam going through our mail servers.

In particular, I like the coverage of white and blacklisting, bayesian filtering and tweaking spam hits scores.
