so it appears your SA Bayesian database is screwed up. Did you train the database with known spam and non-spam beforehand? Did you use actual mail for the domain(s) you manage?<br>
<br>
Here's a starting suggestion. Turn of Bayes in SpamAssassin by setting<br>
<br>
use_bayes = 0<br>
<br>
in /etc/mail/spamassassin/<a href="http://mailscanner.cf" rel="noreferrer" target="_blank">mailsca<wbr>nner.cf</a>. If that helps with correctly classifying spam, then I'd delete the Bayes databases and rebuild them with new bodies of spam and non-spam messages.<span class="gmail-HOEnZb"><font color="#888888"><br>
