Hey all. If you're like me you probably get in the range of 250-300 spam messages per day. I used to use Cloudmark Spamnet before it went pay-ware and it did pretty good. Recently I've been using an open source program called SpamBayes. It uses Bayesian analysis and so far has done an EXCELLENT job. Best of all it's free and continually being developed. If you want to give it a shot, head on over to
