Chris,
Maybe you should take a different approach and try to block spam as a whole?
If your front end mailserver is *nix-based, I can recommend Spamassassin
(http://www.spamassassin.org); easy install and pretty tweakable.
On my system I now actually see 2-3% of the spams I did previously; the rest
is just archived for later review just in case there is a false positive.
Best regards,
-Allan Jensen
