DKIM

(DomainKeys Identified Mail) An email authentication method that computes a digital signature which is added to the message header. The receiving mail server obtains the sender's public key from the DNS system to validate the signature. In 2004, Yahoo! began to sign all outgoing mail with DKIM headers, and other mail services followed.

Yahoo! and Cisco = DKIM
Yahoo!'s DomainKeys was combined with Cisco's Identified Internet Mail system, which maintains signature consistency, to become DKIM. DKIM is backward compatible with the DomainKeys system. See email authentication, Vouch By Reference and digital signature.

DKIM and SPF have been used by a number of companies for several years.
As protocols like SPF, VBR and DKIM become widely used they increase the likelihood that spam will be detected and that valid mail will make its way safely into the recipients' inboxes.
Currently these proposed authorization schemes are called Sender-ID, and a new scheme called Sender Signer Policy (SSP) that is intended to work with DKIM. As with Sender-ID, SSP also makes the assumption of being an indirect method of source identification, and even directs complaints to the email address domain owner.
DMARC allows a sender to mark in their e-mails whether they are protected by SPF and/or DKIM, and notifies the receiver what to do if neither of those authentication methods passes such as send to junk or reject the mail.
"Whether you are an enterprise or offering a consumer service, you can apply this policy now," says Brett McDowell, senior manager of customer security initiatives at PayPal, who is chairman of the organization DMARC, which stands for "Domain-based Message Authentication, Reporting and Conformance." The DMARC.org site today published guidelines and the specification for its technology, which makes use of the well known standards Sender Policy Framework (SPF)and Domain Keys Identified Mail (DKIM), two basic approaches widely used today for authenticating email.
Almost a decade after the industry last set out to solve the problem with DomainKeys Identified Mail (DKIM)and Microsoft's Sender Policy Framework(SPF, later called Sender ID), DMARC's arrival is an acceptance that these have not been enough.
