Yes it does, but it only auto-learns very high and very low scoring
mails.  Odds are that the mails your users would want to train it with
would be more moderate scores, as most false positives/ negatives tend
to be borderline scores.  Therefore this wouldn't work unless you
changed the thresholds to tokenise everything, which would probably not
be a good idea (mis-learning borderline cases, server load, database
size etc).
