Just like Darrin and John, I recommend K9, too.

It is small and fast (compared to PopFile), and it does not lose efficiency
(compared to the TB plugins BayesFilter and BayesIt).

Even though it is NOT a plugin for TB, I find its usage easier and more
comprehensible than the TB plugins. The GUI is simple, definition of white-
and blacklist rules is very easy, and it gives a greater feeling of overall
"control" to the user than the TB plugins do.

After the installation and first configuration, and a short training
period, it needs almost no maintenance - this is the most important thing
for me, I don't want to re-classify mails every other day and tweak some
settings and whatnot.

Following are my K9 statistics. Notice the second column. No false
positives for 190 days. The 37 false positives in the first column were
right after installing K9 and using it for the very first time. I have a
large amount of whitelist matches because all mailinglists I'm on are
whitelisted and not used for training the K9 database.
