Please help with spam problem. I use Zimbra open source edition for our company email server and use external spam-relay wich tags spam for us and relays the emails to our Zimbra server. In Zimbra I have setup Inbound SMTP host name setting for that spam-relay.

Our MX records are set for spam-relay, and all emails go trough spam-relay, I get the report for each email taged as spam from relay and the scores. Once the spam email finishes in recipient inbox it has new recalculated spam scores. I want to use those set by spam-relay not the ones set by Zimbra.

Thank you.
