How do I set up an MX record on my domain name?

This article will show you how to create an MX record for your domain name.

Before proceeding, you’ll need to ensure your domain is pointed to the 123 Reg nameservers. Otherwise, any configurations you’ve made to the DNS through our Control Panel will not take effect.

You will need to set your DNS at your nameserver provider. For more information on how to do this, please view the following article: How do I change the nameservers for my domain name?

Please note: it will take between 24-48 hours for any nameserver changes to become active.
