A week later and... my attempts at retraining the bayes database aren't
working. It is looking more like we're going to have to start afresh
with a new bayesian database.

In the next couple of days (unless the bayes filter magically fixes
itself) I'll be backing up the current bayes db and letting spamassassin
create a new empty one. Note that the bayes db won't be functioning at
all (better than marking spam as not-spam though) until it is trained
with ~500 pieces of mail.

And did those feet in ancient time
Walk upon England's mountains green?
And was the holy Lamb of God
On England's pleasant pastures seen?
