Simply telnet to mailserver on port 25 and type what I've shown,
substituting valid email addresses and valid addresses in your domain as
indicated. You can use your own domain for the hello command, i.e. "helo
mydomain.com". Everything between the data command and the '.' is input
to the data command. After you type the '.' the message will be sent
and should be delivered to the user on the "rcpt to" line. You should
see logging of successful delivery or errors in the maillog.
