Oh blimey, you know how sometime you can do things because you think
they make no difference, but you kinda forget it by the time you come to

For what it's worth, I shall never again think that commenting out the
"use_bayes 0" in spam.assassin.prefs.conf is a good idea. Any mistaken
belief that this would have no effect will never again enter my mind.
