Do the Impossible
The port number that email is transferred on from server to server, 25, is a hard-coded, unchangeable value. Mail servers that want to do business on the Internet must talk on this port. But many ISPs have decided to block port 25 to protect their customers and have effectively prevented the home or office email server!
No-IP researched the problem and came up with a solution: Mail Reflector. Mail is first delivered on the standard port to our mail system and then is immediately delivered to your mail server on whichever port you specify. This gives you complete control of your mail system and bypasses seemingly insurmountable restrictions.
Mail Reflector also provides all the features of Backup MX, including virus filtering, greylisting, and customizable RBL lists, so that even if your mail server is temporarily unavailable, mail will not be lost. Do what was once impossible: Run your own mail server.
