DKIM stands for DomainKeys Identified Mail, and it is an email authentication mechanism that allows an organization to take responsibility for sending a message, so it can be validated by the recipient. cdmon does not provide DKIM authentication services, but it does allow you to create a DKIM entry in DNS. This means that if you use cdmon DNS services but your email service is hosted with another provider, you can create a DKIM entry in DNS using the values provided by your email provider.
To configure a DKIM entry, you must access DNS management directly by clicking on the DNS option from the "Basic service list" in your control panel and follow these steps.
1.- Add record
In the "DNS Records" list, click on New record and in the "Record type" dropdown select TXT/SPF.
On the next screen, in the "Redirect" section, select the option A specific subdomain.
In the "A specific subdomain" option, you must enter the 'Selector' in the "Subdomain" field, which usually has a value similar to: dkim._domainkey. In the "Value" field, you must enter the key provided by your email provider.
Once all values have been entered, click on Save record.
2.- Propagation
Your TXT record has now been created. You only need to wait for the changes to propagate, which may take approximately five minutes.
