Determining if SMTP Authentication is enabled
You can use telnet to verify if the server's response to the SMTP commands is
enabled on an e-mail server.

Connect using the well known port for SMTP (Port 25). Ensure that your
telnet application is enabling a local echo.
Result: The following message appears:
220 SERVERNAME.DOMAIN.COM ESMTP Server (Microsoft
Exchange
Internet Mail Service 5.5.2650.21) ready
2 Type HELO.

command:
MAIL FROM: anymailbox
250 OK - mail from <anymailbox>
4 Specify recipients using the RCPT command.

RCPT TO: anyone@externaladdress.com
550 Relaying is prohibited
Otherwise, you receive the message:
RCPT TO: anyone@externaladdress.com
250 OK - Recipient <anyone@externaladdress.com>

send an e-mail message using the DATA command:
