You're making the telnet connection, but unless you left part of the
"action" out, the mail server is not responding with the SMTP connection
banner. So it appears you can reach the machine's port 25, but the SMTP
server dislikes you enough to refuse even to begin to talk to you.
It should look something like this:
$telnet smtp.olympus.net 25
Connected to smtp.olympus.net.
Escape character is '^]'.
220 entiat.olympus.net ESMTP Exim 4.42 Wed, 22 Dec 2004 16:49:48 -0800 C
Where that 220 line is the "missing" banner (and the trailing " C" is an
indicator we added to this instance of Exim).
