Thunderbird has built in Bayesian spam filtering.. Just go into options
and enable junk mail control.  From that point forward, as you mark
messages as Junk, you will be training the filter.  Just remember, when
you first start using this feature, you have to go into your Junk folder
and find messages that were marked as Junk in Error, and mark them as
non-junk.  High false positives are common when you first start
filtering with Thunderbird, but the filter will adapt very quickly once
you mark a few as non-junk.

By default, Thunderbird is configured so that people in your address
book are automatically white-listed.  This ensures that the people you
have e-mailed correspondence with are never accidentally junked, but
since spam generally uses spoofed <from> headers, some junk will get
through by being <from> your friends.  If this annoys you, you can turn
that off.

And finally, once your filter is somewhat trained, you might find lots
of junk is still getting through.  If you go into Preferences ->
Advanced -> Config Editor, and search for junk_threshold, you will see
the default is a very conservative 90.  The lower this number, the more
strict Thunderbird will be about deciding something is Junk.  I'm
personally very comfortable with 60 on my system.
