Since the only objective is to keep Bayes up to date, just run INPUTMSG
through sa-learn. Why keep it around? However, this will dump any false
positives into the DB, which may not be what you want. It's probably best to
quarantine low scores in a spam trap and auto-learn and discard only the
egregious stuff.

In my experience setting the "egregious threshold" to 10 takes care of almost
2/3 of spam, making it much easier to manually check the remainder while
virtually eliminating false positives in the discarded mail.
