I am using postfix, and I did the above. (The default for postfix,
according to the main.cf is "inet_interfaces = all".) I am still unable
to get to that port.
I am able to get to it from another system on the same network though.
tcp 0 0 0.0.0.0:25 0.0.0.0:*
LISTEN 0 753682 14311/master
tcp 0 0 209.25.194.148:25 209.25.194.146:1445
ESTABLISHED 89 757846 14650/smtpd
tcp 0 0 :::25 :::*
LISTEN 0 753681 14311/master
I don't see anything that jumps out at me about postfix accepting
connections from something outside of it's local network.
