DomainKeys Identified Mail

From Wikipedia, the free encyclopedia

DomainKeys Identified Mail is a method for E-mail authentication. It offers almost end-to-end integrity from a signing to a verifying Mail transfer agent (MTA). In most cases the signing MTA acts on behalf of the sender by inserting a DKIM-Signature header, and the verifying MTA on behalf of the receiver, validating the signature by retrieving a sender's public key through the DNS.

The DomainKeys specification has adopted aspects of Identified Internet Mail to create an enhanced protocol called DomainKeys Identified Mail (DKIM). This merged specification is the basis for an IETF Working Group which has guided the specification towards becoming an IETF Proposed Standard.

See DomainKeys for details of the general method of operation used; DKIM is very similar in most respects to DomainKeys' operation.
