I have been following the Perfect Server Setup for Ubuntu 8.04, but I am not able to get a response from telnet. The only response that I receive is as follows: telnet localhost 25 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. Then it just sits there. I never get the following line so I can type in 'ehlo localhost' 220 AOP1.AOPserver.com ESMTP Postfix (Ubuntu) And when I mean that it just sits there, I left it alone for over 5 hours and never received a response on it. Anyone got an idea on what's happening?
