Mail not routing to SCM 3100
Posted on 2008-10-01
Anyone know anything about using the McAfee SCM3100, or more specifically, how to get mail to actually go to it?
I've got two backend exchange servers and a front end exchange server (all Exchange 2003). I've got an SCM3100 set up in explicit proxy mode. In external DNS, the SCM3100 is priority 10 (the MX record, I mean), the FE exchange server is priority 20, the BE exchange server priorities are 30 and 40 respectively.
The SCM is filtering email, but not much is getting to it. It's online and some email is going right to it, but thousands of other spam mails are getting right though without being filtered, and they fit content / spam rules that should be blocked. I think these emails are, for whatever reason, going straight to the FE exchange server, bypassig the SCM appliance even though it's the highest priority MX record. I must be doing something wrong in DNS; when I remove the MX record for the backend exchange servers, they can't send email, so I have to leave them up there.
Any ideas on what I'm doing wrong?
