I'm trying to fine tune my spam filtering. I have some done by my gateway (Sophos UTM 9) and use Spam Assassin on my Kerio server. My gateway flat out blocks everything for which it gets a positive reply on a BL, and sorbs has lots of false positives, so I'm hoping to use Kerio's blacklist and just add to the spam score so false positives will land in users' spam folders but they'll at least still get them.

Anyway, the blacklists don't seem to be getting used by Kerio and I can't figure out why. Do blacklists like use special ports for sending message headers and getting results back? I checked their site obviously and couldn't find anything. I'm wondering if I need to forward something to my mail server besides normal email/kerio/exchange ports (SMTP, HTTPS, etc) for the blacklists to work.

When I turn on message filtering in the debug logs, nothing from sorbs shows up, so I'm assuming it's not even calling it; but I"m not sure if the problem is on the way out, on the way back, or the server its just broken or set up wrong.
