SMTP Restrictions is a feature in WHM that stops users from bypassing the mail server to send mail.  This service is useful because bypassing mail servers is a common practice of spammers.  By setting up restrictions you’ll only receive mail from root connections, Mailman mailing list software and mail transport agent (MTA) to remote SMTP servers.
