Hi, I use a Spamassasin version 3.3.1 on Windows System and I have a
problem with Bayesian filter:

-A legitimate users send an email to our server and they are delivered
normally

-When that users insert it’s domain in the email signature the email is
marked as spam with that header:

oX-Spam-Status: Yes, hits=2.8 required=2.0
tests=BAYES_99,BAYES_999,HTML_MESSAGE,RCVD_IN_DNSWL_LOW,SPF_PASS
autolearn=no version=3.3.1

oX-Spam-Score: 2.8

-After a few try I have noticed that if I remove the domain line form
the signature the email is delivery correctly

-That users report that the problem is the same on many server (I think
that’s because all use BAYES filter

How can I inform the manteiners of Bayes Filter of this false positive?

a bayse relies on proper training



what says "sa-learn --dump magic"

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