DomainKeys Identified Mail (DKIM) is an email authentication system designed to detect email spoofing. It allows organizations to take responsibility for transmitting a message, while providing a mechanism to verify that the message was not altered during transit.  DKIM uses cryptographic signatures and public-key infrastructure to verify that an email message has not been altered during transit, and that it truly came from the claimed sender. Email senders can use DKIM to sign their messages by adding a DKIM-Signature header field to the messages. Email receivers can then use the public key published in the DNS to verify the signature and check that the message has not been tampered with. 

Steps to Configure DKIM for Cakemail

In your DNS, post the following DKIM record:

Hostname/Name/Host: dkim._domainkey.domain.com  

Type: CNAME

Value: dkim._domainkey.md02.com

Note: Your DKIM selector is indicated by “dkim” at the start of the record. Substitute your own domain name with domain.com.

Use our free DKIM record lookup tool to validate the published DKIM record.
