 FAQ


Why SMTP Redirect?

         Is your ISP blocking incoming SMTP port 25, but you still need to run an email server?

Our Mail Redirect service allows you to relay incoming mail to a mail server on a non-standard port. This is perfect for those who want to operate a mail server despite an ISP block on the standard email port 25. Flat price at $29.99 per domain per year.

Understanding SMTP Port 25



All email sent via the Internet is routed through port 25. When an email server on your computer delivers messages, it always uses port 25 to transmit data to remote email servers. If your ISP blocks incoming port 25, your emails won't reach your mail server.

Here's How Mail Redirect Operates:

Run your mail server on a non-standard SMTP port
Assign SMTP.dnsexit.com as your domain's primary MX
The following shows how emails get routed:
email@yourdomain.com smtp.dnsexit.com : 25 smtp.yourdomain.com : 26, 940, 587, 8001 (non-standard SMTP port)
Primary Mail Exchanger

We act as your domain's primary mail exchanger, storing and forwarding emails for your domain. Port 25 is open to us, so mail clients can connect without issues.
Email Routing

All emails to your domain are routed to our server, which stores and forwards them to your mail server listening on a non-standard port that your ISP doesn?t block.
Redundancy

Enjoy redundancy similar to Mail Backup MX. Our server will spool emails for 5 days or 30 days (extended) if your server is unavailable, with a maximum mail size of 60 MB.
