SpamBully - Bayesian spam filter
I'm an experienced user spam filter user. I used to use SpamInspector, plus used SpamArrest (online server) to add a challenge email step to one of my accounts...
recently I discovered another filter at www.spambully.com.
SpamBully was rated BEST BUY in October 2003 WIRED Magazine:
I have downloaded trial, and love it!
SpamBully does it all - I have even been able to delete all of my old, manually entered spam-filtering rules - the Bayesian wizard is phenominal out-of-the-box! Now mine is trained, I am seeing 99%+ accuracy (in fact, for the past 24 hours, I've seen 100% accuracy!)
