result, and I also had to set a couple of macros in my email client, mutt, for
marking emails as spam or ham (to correct errors when SpamAssassin gets it
wrong). I've also heard that you need to train the Bayesian filter on a fair
number of messages before it can give you any useful results, so that may take a
