What are some ways to better "lock down" spam filtering with SA. I setup
RBL and XBL filtering in my smtpd run script and that knocked out a lot
of incoming spam...but I am still getting a lot through. I am also
running qtrap, which is catching a lot of email for banned words...I
would think that SA would cath spam before qtrap...so clearly I am not
doing something right. I have sa-learn setup to run ham and spam each
night...and those learned spam are still getting through. Is there some
"flag" that I am have setup right?
I set spam_bayes 1 and restarted SA (a couple months ago).
