there is a drawback in this setup in if users send a blacklisted url then
its learned as ham, and this will then score incomming mail with that url
as more ham likely

how to solve this imho is to scan outgoing same as all incomming, and let
all scores be considered if or not its ham or spam in the learning, your
setup force learning based on auth, only half as good as let it be score
based

just my 2€ :)
