DomainKeys Identified Mail Signatures
RFC 4871, “DomainKeys Identified Mail Signatures”, is a Proposed Standard document published in May 2007 by E. Allman, J. Callas, M. Delany, M. Libbey, J. Fenton, M. Thomas. It obsoletes RFC 4870. It has since been updated by RFC 5672. It has been obsoleted by RFC 6376 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
DomainKeys Identified Mail (DKIM) defines a domain-level authentication framework for email using public-key cryptography and key server technology to permit verification of the source and contents of messages by either Mail Transfer Agents (MTAs) or Mail User Agents (MUAs). The ultimate goal of this framework is to permit a signing domain to assert responsibility for a message, thus protecting message signer identity and the integrity of the messages they convey while retaining the functionality of Internet email as it is known today. Protection of email identity may assist in the global control of "spam" and "phishing". [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
