[Bug 9870] Re: Better spam filtering for evolution

Because self-learning filters generally perform a lot better after being
trained, when considering both false negatives (no problem if there
aren't many) and false positives (even 1 might get you in trouble).  As
(almost) every RBL I know causes lots of false positives, I don't think
they are a good idea.

Also, it would make it possible for a third party to hurt Ubuntu users
badly (those RBLs are not under our control).
