ThunderBird Junk Mail
For some reason, ThunderBird 1.0.7 ’s (yeah, I’m still using that…) Junk Mail filter doesn’t seem to improve fast after regular training. It’s supposed to be bayesian implemented correctly (*shrug*). Will check out TB 1.5 RC1, and may get some time into looking at how it’s implemented.
OTOH, X-Spam-Flag headers are working nicely.
