DKIM is a popular email authentication protocol that exists in your DNS as a TXT record that helps in authenticating messages sent from your domain. DKIM signs your outbound messages with a cryptographic signature that is matched against a public key that resides in your DNS by the email receiving MTA. If it is a match, messages pass DKIM. DKIM along with DMARC helps to make your emails safe again.
