DomainKeys Identified Mail (DKIM)

DomainKeys Identified Mail (DKIM): DomainKeys Identified Mail (DKIM) lets an organization take responsibility for a message while it is in transit.� The organization is a handler of the message, either as its originator or as an intermediary. Their reputation is the basis for evaluating whether to trust the message for delivery. Technically DKIM provides a method for validating a domain name identity that is associated with a message through cryptographic authentication.
