Hi,
I'm afriad I can't help you there (yet!). I'm still in very early stages. I'm trying to get SA to just tag all messages it thinks are spam (not to delete anything), then let the mail client file (or delete) stuff depending on the score.
I'm worried about automatic deletion as it is all to easy for false positives (tagging genuine e-mails as spam) and if they are getting deleted - you'll never know you were meant to get it!
Once we've bothed worked out what to do we should have a chat and see if we can't combine our knowledge to get the best setup
Regards
Paul
