Looks like I need to test this with 2.3a1... I'm downloading it now.

In pop3proxy, the training (ie. the calling of Classifier.learn()) is done
when messages are moved from the Unknown corpus to one of the Ham or Spam
corpuses.  This code:

            # Create the Trainers.
            self.spamTrainer = storage.SpamTrainer(self.bayes)
            self.hamTrainer = storage.HamTrainer(self.bayes)

sets up trainers which automatically train the classifier when messages are
moved between corpuses using Corpus.takeMessage(), which is called by
onReview().  This code is missing from proxytrainer.py - overzealous code
trimming?  8-)
