>> 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 220.127.116.11...
>> 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 [18.104.22.168], pleased to meet you
>> Does the mail server ever return anything back to you?
> No. Never. How do I trouble-shoot this?
Do you have anything like greylisting or greetpause running?
