The Stub,

I tried the Thunderbird spam checker for two weeks and got no where with it. Even with much training, it let 80% spam through on my computer. :cry:

SpamPal (which I use) has more than a 90% accuracy before it was even trained with the Bayesian filter. That is because it also uses good words, bad words, Blacklists, Whitelists, and other plugins along with Bayesian filtering. Now it has better than 98% accuracy. ;D

Basically, you need to chain them together. Have fun.
Yea, load's of fun. ::)
