Turn it on and set all the BAYES_* scores to 0.01, then look for
BAYES_[6789] in ham. You can do that in your mail log on the server
without violating anybody's mailbox privacy.
The reliability of Bayes is based entirely on how well you train it.
And again, you might consider turning on greylisting for sites you don't
regularly correspond with, to allow URIBLs time to list new spam domains.
