How do I set up a DKIM record on my domain name?

This article will show you how to set up a DKIM record for your domain name.

You can use DKIM (DomainKeys Identified Mail) to add an additional level of security to the email you send via your domain name.

To set up a DKIM record on your domain name, you’ll first 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 new 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 Domain Names within the ‘Manage active products’ section. Next, choose your domain name from the provided list and then select Manage.

Manage Domain Names


Step 3 of 5

Scroll down to the Advanced Domain Settings section and click 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 TXT/SPF from the drop-down list
  • In the Hostname field, enter the hostname you’ve been provided with (i.e. sl_domainkey)
  • In the Destination TXT/SPF field, enter the DKIM record that’s required

    Once done, click Add to save the new record.

Enter DKIM Details

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