DKIM is an email authentication method that authorizes the email and makes sure if the email was sent from a legit and not a fraudulent source. This is done by verifying the DKIM signature that is added with the email and is encrypted. MessageGears handles the DKIM for all its users by providing the DKIM TXT record, all you have to do is publish the TXT record via your DNS. Follow the steps to publish the TXT records through your DNS :
Setting Up DKIM for MessageGears
Publishing DKIM record in DNS
Log in to your DNS management console
Create a TXT record in your DNS with the title : <selector>._domainkey.<yourdomainname.com> for example: s1._domainkey.yourdomainname.com
In the section allotted for the TXT record value, paste the copied contents of the DKIM public key (the DKIM public and private key pair will be provided by MessageGears on request)
Lookup and validate the published DKIM DNS record using this free DKIM record lookup tool
