v1.0.1 Pretty Cool Rated 4 out of 5 stars

It's excellent at identifying spam; pretty good at identifying possible spam (though a blatant Viagra mail slipped through - maybe I haven't trained it enough yet). One minor point is that even though I've made a new 'Spam' folder and checked the box in the prefs to move spam to it, at the moment Thunderbayes doesn't seem to want to move the mail from my inbox. But overall a very useful addition to Thunderbird's built in junk filter, especially if you're being bombarded by f*****g spammers. Set up is very easy if you're thinking about trying it out. One of the best Thunderbird add-ons I've installed.
