"DomainKeys Identified Mail (DKIM) Service Overview", Tony Hansen, Dave Crocker, Phillip Hallam-Baker, 11-Jul-08. ( bytes)

This document provides an overview of the DomainKeys Identified Mail (DKIM) service and describes how it can fit into a messaging service. It also describes how DKIM relates to other IETF message signature technologies. It is intended for those who are adopting, developing, or deploying DKIM. DKIM allows an organization to take responsibility for transmitting a message, in a way that can be validated by a recipient. The organization can be the author's, the originating sending site, an intermediary, or one of their agents. A message can contain multiple signatures, from the same or different organizations involved with the message. DKIM defines a domain-level digital signature authentication framework for email, using public- key cryptography, using the domain name service as its key server technology [RFC4871]. This permits verification of a responsible organization, as well as the integrity of the message contents. DKIM will also provide a mechanism that permits potential email signers to publish information about their email signing practices; this will permit email receivers to make additional assessments about messages. DKIM's authentication of email identity can assist in the global control of "spam" and "phishing. (This Internet-Draft is also available in PDF format [ bytes].)

"DKIM Author Domain Signing Practices (ADSP)", agent Local-part, Eric Allman, Jim Fenton, Mark Delany, John Levine, 19-Sep-08. ( bytes)

DomainKeys Identified Mail (DKIM) defines a domain-level authentication framework for email to permit verification of the source and contents of messages. This document specifies an adjunct mechanism to aid in assessing messages that do not contain a DKIM signature for the domain used in the author's address. It defines a record that can advertise whether a domain signs its outgoing mail, and how other hosts can access that record.
