Domain Keys Identified Mail (DKIM, RFC 6374) currently has an IETF standards status of Draft Standard, which is now an obsolete status. This note requests reclassifying it to Internet Standard. (1) There are at least two independent interoperating implementations with widespread deployment and successful operational experience. DKIM is in large-scale production use around the Internet, and there are many independent implementations of DKIM. See http://dkim.org/deploy/ (2) There are no errata against the specification that would cause a new implementation to fail to interoperate with deployed ones. There is only one, non-substantive erratum against an example in the DKIM specification: http://www.rfc-editor.org/errata_search.php?rfc=6376 (3) There are no unused features in the specification that greatly increase implementation complexity. The -bis effort that produced RFC 6374 at Draft Standard refined the document against implementation and deployment experience, and eliminated unused features. (4) If the technology required to implement the specification requires patented or otherwise controlled technology, then the set of implementations must demonstrate at least two independent, separate and successful uses of the licensing process. The Yahoo! IPR declaration does not require users of the technology to pursue special procedures, such as licensing: http://datatracker.ietf.org/ipr/693/
