> Something isn't quite right with your setup. When you do the "HELO" command, the server should reply with something. For example: > > == > $ telnet smtp.comcast.net 25 > Trying 76.96.40.155... > Connected to smtp.comcast.net. > Escape character is '^]'. > 220 omta12.emeryville.ca.mail.comcast.net comcast ESMTP server ready > HELO comcast.net > 250 omta12.emeryville.ca.mail.comcast.net hello [69.24.1.7], pleased to meet you > == > > Does the mail server ever return anything back to you? No. Never. How do I trouble-shoot this? TIA, John
