"DomainKeys Identified Mail (DKIM) Author Domain Signing Practices (ADSP)", header field, Author Domain, return error, Eric Allman, Jim Fenton, Mark Delany, John Levine, 11-May-09. ( 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.

"DomainKeys Identified Mail (DKIM) Development, Deployment and Operations", Tony Hansen, Ellen Siegel, Phillip Hallam-Baker, Dave Crocker, 11-Jul-09. ( bytes)

DomainKeys Identified Mail (DKIM) allows an organization to claim 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 document provides implementation, deployment, operational and migration considerations for DKIM.

"RFC 4871 DomainKeys Identified Mail (DKIM) Signatures -- Update", Dave Crocker, 26-Jun-09. ( bytes)

This updates RFC 4871, DomainKeys Identified Mail (DKIM) Signatures. Specifically the document clarifies the nature, roles and relationship of the two DKIM identifier tag values that are candidates for payload delivery to a receiving processing module. The Update is in the style of an Errata entry, albeit a rather long one.
