Something isn't quite right with your setup.  When you do the "HELO" command, 
the server should reply with something.  For example:

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

Does the mail server ever return anything back to you?

Sometimes, if you are traversing a firewall between you and the mail server the firewall blocks the connection because telnet uses the tcp PUSH flag.
