What is a DomainKey record?

DomainKeys Identified Mail (DKIM) is an authentication standard used to prevent email spoofing. This TXT record will contain a public key that’s used by receiving mail servers to verify a message’s signature. The DKIM public-key cryptography process allows recipients to be confident of a sender’s authenticity.
