> 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 18.104.22.168...
> 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 [22.214.171.124], pleased to meet you
> Does the mail server ever return anything back to you?
