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

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.
