DomainKeys

An e-mail 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 DomainKeys headers.

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

A different way to authenticate a message is by using a cryptological key-based approach, such as Yahoo's DomainKeys. The ISP that releases an e-mail onto the public Internet applies some form of signature that ties the identity of the sender to the content of the message, Thielens says, and when it arrives at another ISP, specialized software can perform an analysis to ensure that a message goes with a particular e-mail address.
