What is DKIM?

DKIM (DomainKeys Identified Mail) adds a digital signature to outgoing emails, allowing receiving servers to verify that the message was sent by an authorized server and hasn't been tampered with in transit.

DKIM records are stored as TXT or CNAME records at selector._domainkey.yourdomain.com. The selector is chosen by your email provider.
