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
Do you have anything like greylisting or greetpause running?
