If you're not sure what CNAME records are, ask your domain host for assistance. When you phone or email their support team, you can use the email template below. Follow the steps below to add the CNAME record to your domain host. More detailed information can be found in the documentation provided by your domain host. The DNS settings in our example case are handled by Cloudflare.

Step D: Verify the status of your domain

After you've modified the CNAME record, go to the domain menu in the SMTP Server program and verify the status of your domain. If all records have been properly updated, the Active status will be displayed; otherwise, the status will be Pending. If the status remains Pending after 5 minutes, double-check the CNAME record or contact our support team.
