I'm not sure wiping BAYES is needed, unless training does not
He has autolearn running. Unless he has copies of the spams that were
learned as ham, there's no way to totally undo that short of wipe and
start over from scratch.
You *did* keep your initial Bayes training corpora, right?
this is very good idea to have. Maybe at least keeping all autolearned spam
and ham for some time, just for the possibility of retraining.
The critical part is to have base corpora of *correctly classified* (i.e.
manually reviewed) messages. If you're keeping copies of autolearned
messages (which will probably be quite a few) then you *need* to *manually
review* them before using them for retraining, otherwise you'll probably
end up simply rebuilding a mistrained database.
If you have users submitting FP/FN messages for training, and the admin
verifies them before training with them (which should be done unless the
judgement and responsibility of the user in question is trusted), that's a
good source for part of your base retraining corpora.
