autolearn - The default is for SA to feed into Bayes anything that
scores high enough (as spam) or low enough (as ham). I agree that this
is a fundamentally and philosophically flawed idea. At the least it
should not be a default and should use much further thresholds than it
did when I last checked.
If you weren't aware of this, this may be how your Bayes DBs ended up
poisoned. With autolearn it can happen anytime a new style of spam
comes through which is not caught by SA's existing rules.
