We have a 5510 (8.2) with the following 4 interfaces (security-levels) inside (95), outside(0), dmz(25), and test (95). The dmz network is 10.10.10.0/24 and the outside interface is 220.127.116.11.
We have run into a situation where a dmz hosted iRedMail server running postfix (10.10.10.51) is relaying mail which in some cases points back to us at 18.104.22.168 and into our Exchange server. In these cases in the dmz server's mail logs we see postfix timeout trying to connect to smtp at 22.214.171.124. When I try to telnet from 10.10.10.51 to the outside interface on port 25 it times out.
We've tried different ways to allow the outside adapter to permit smtp (or any service!) from 10.10.10.51 but we're left scratching out heads.
