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. eric
