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.

Please note: 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?

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 5

Start by logging in to your 123 Reg Control Panel.

 

Step 2 of 5

From there, select your desired domain from the drop-down menu within the Manage Active Products section and click Manage.

Alternatively, you can scroll down to the Domain names section and select the relevant domain name from the drop-down menu. Once selected, click Manage.

Manage Domain

 

Step 3 of 5

Scroll down to the Advanced Domain Settings section and select Manage DNS.

Click Manage DNS

 

Step 4 of 5

Select the Advanced DNS tab near the top.

Select Advanced DNS

 

Step 5 of 5

On the next page, create a new record with the following information:

  • In the Type field, select MX from the drop-down list
  • In the Hostname field, enter an @ symbol
  • In the Destination MX field, enter your mail server’s address. If you’re using 123 Mail, then you should use the following records: 123-reg.co.uk and mx1.123-reg.co.uk
  • In the Priority field, you’ll be given a value by your email service provider. If you’re using our MX records, we recommend that you use 10 (mx0.123-reg.co.uk) and 20 (mx1.123-reg.co.uk)

Once you’ve entered your details, select Add to complete the process.

Enter MX Details

Important: MX records must be terminated with a full stop, or they will not work correctly.

Please note: it will take between 4-8 hours for any DNS records to become active, provided you didn’t also change the nameservers.
