How do I set up my domain name to point to my own mail Server?

If you intend to run your mail services via a hosted exchange service or a dedicated mail server from another provider then the below instructions will ensure that your domain is pointing to that mail server.

Email servers need a domain name to function correctly, some email systems will not except an IP address.

When you set a domain’s DNS to use a mail server, you have to provide a domain.

It is standard practice to create a new sub domain and resolve the sub domain to the correct mail server IP address, then update the domain to use the new mx server.

The advantage of using this method is if you change your mail server IP address you need only need to update the sub-domain MX Record and not have to make serveral DNS changes.

To setup 3rd party mail servers for your domain name, please do the following:

1

Login to your 123-reg control panel.
