Users have only been using the Junk button. I just don't see anything in the HAM account and from the above post it sounded like there needed to be 200+ messages in each of the SPAM and the HAM accounts inorder for spamassassin to work correctly.
There is no catchall account, and I guess my next step would be to reject mail from unknown users.
Which comes to your third point and my main dilemma, I can't figure out why emails which are classified as Junk by users are still passing through with low scores. There have been quite a number of instances where they are identical emails and they still pass through. |
