normally i would expect that behavior triggered by URI blacklists which 
did not hit in the tests - if it is really bayse than it means a lot of 
messages containing this domain are trained as spam and none as ham

a bayse relies on proper training

meaning you need at least the same amount ham samples for a really good 
working one as you have spam samples

what says "sa-learn --dump magic"
