Hm. This doesn't actually look like postfix. Do you have something else running on that machine that accepts mail and then passes them on to postfix?
No, it's just postfix & cyrus for mail.
Is the firewall perhaps a proxy, and not a simple firewall reverse NAT? If so, then postfix would see the mail as coming from the actual firewall machine, which is on the local LAN, which would explain why it sees it as trusted.
That I can't say. The firewall is a separate box, made by Symantec, which I have no control over, other than asking for ports to be forwarded. I guess I'll have to see what's actually in the packets and enquire about the firewall being a proxy. tnx for the idea.
