Domain Keys

DomainKeys is an email authentication system designed to verify that an email message was sent by an authorized sender and has not been altered during transit. It works by attaching a digital signature to the header of an email, which the receiving mail server can then cryptographically validate using a public key published in the sender's DNS records. This process helps prevent email spoofing and ensures that the integrity of the message remains intact from the source to the destination.
