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.

MX records are a specific DNS record that shows the mail server responsible for accepting emails to your domain name. Without them, providers won’t know which mail server your messages should go to and, as such, you won’t receive any emails. Most domains include at least two MX records so that one can serve as a backup.

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.

Once you’ve done this, simply follow these instructions:

Step 1 of 6

Start by logging in to your 123 Reg Control Panel.

Step 2 of 6

Next, select Manage All opposite Domains within the ‘All Products and Services’ section.

Step 3 of 6

You will now see a complete list of your purchased domain names. Select the domain you want to update from the provided list.

If you can’t find your domain in this list, you may be able to find it on the Domain Name Overview page within our legacy Control Panel. For more details on this, please read the following article: How do I access and manage my products?

Select Domain

Step 4 of 6

If you’re using our current Control Panel, select DNS in the navbar.

If you’re using our legacy Control Panel, click Manage DNS within the Advanced Domain Settings section.

Step 5 of 6

If you’re using our current Control Panel, you will now see a list of DNS records for your domain. From here, click Add New Record.

If you’re using our legacy Control Panel, select the Advanced DNS tab near the top.

Step 6 of 6

Next, add two new records using the following information:

For Generation 2 mailboxes

Name/HostnameTypePriorityValue/Destination MX


For Generation 1 mailboxes

Name/HostnameTypePriorityValue/Destination MX

Please note: MX records must be terminated with a full stop, or they will not work correctly. It will take between 24-48 hours for any DNS records to become active, provided you didn’t also change the nameservers.
