After confirming your domain, click the Authenticate option on the Manage Domains page.
You will see a dialogue box with instructions on what CNAME record to generate and what values to put in it so that DKIM is configured. It instructs you to set up a CNAME record for the domain name k1. domainkey.domain.com with the following value: dkim.mcsv.net.
Put the CNAME record into effect in your DNS and give it up to 24 to 48 hours. In the dialogue box, select Authenticate Domain to configure DKIM and finish the authentication procedure.
Next, you can use our free DKIM record lookup tool to look up and verify your DKIM record.
