So I go to this page and get an example of how to do this: http://www.freebsdwiki.net/index.php/SMTP,_testing_via_Telnet and follow the example:
[root@mydomain john]# telnet 127.0.0.1 25 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. HELO justtesting MAIL FROM: testing@gmail.com RCPT TO: testing@gmail.com DATA To: testing@gmail.com From: testing@gmail.com Subject: testing Date: Tu, Oct 2012 10:21:11 -0500 Testing . QUIT
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 250 omta12.emeryville.ca.mail.comcast.net hello [69.24.1.7], pleased to meet you ==
Does the mail server ever return anything back to you?
