I use a Web- and Mail-Server (Apache2 and Postfix) with Suse 8.2 behind a firewall (Cisco 1710 Router with ACL).
Internet < ---- > Router < ---- > Web-, Mail-Server < ---- > PIX < ---- > Intern
X.X.X.X 10.10.0.0/16 DMZ network
permit tcp any host X.X.X.X eq www
permit tcp any host X.X.X.X eq smtp
www works fine !
I can send emails from the mailserver, I can't receive emails to addresses user@domain or user@X.X.X.X
A port scan to X.X.X.X says, that smtp service is not running !!!
I have used the standard configuration (main.cf) with the myorigin, mydomain, mydestination changed.
The MX record was set to the ip-address X.X.X.X
Anyone an idea whats wrong ?
