[NTLUG:Discuss] Postfix Spam Blocking

[Brian]

Paul, I'm looking forward to the answers you get.  I've been using SA
for two years, and have been sorely disappointed.  I believe my
current SA database has learned from 2000 spams and hams, and I still
see the same spams make it through SA, with no change in the bayes
score.  Maybe it's the type of spam/ham I train with, but if that's
the case, then SA is probably not the tool I should be using.

Have you considered using an RBL service?  Highly effective, but
unfortunately you'll end up losing some e-mail from folks who send
from certain IP blocks belonging to major ISPs that have been
blacklisted.
