Technical Summary
Domain-based Message Authentication, Reporting, and Conformance
(DMARC) permits a domain-controlling organization to express domain-
level policies and preferences for message validation, disposition,
and reporting, which a mail-receiving organization can use to improve
mail handling.
DMARC distinguishes the portion of a name that is a Public Suffix
Domain (PSD), below which organizational domain names are created.
The basic DMARC capability allows organizational domains to specify
policies that apply to their subdomains, but it does not give that
capability to PSDs. This document describes an extension to DMARC to
fully enable DMARC functionality for PSDs.
Some implementations of DMARC consider a PSD to be ineligible for
DMARC enforcement. This specification addresses that case.
Working Group Summary
Generally, the working group came to consensus fairly quickly about this proposal because it's fairly minimal, straightforward, and well understood.
However, see the IESG Note below.
Document Quality
There are several expressions of interest with respect to implementation. There is one reference implementation.
Personnel
Murray Kucherawy wrote the original Document Shepherd writeup, and Alexey Melnikov started IETF Last Call
as Area Director. Since then, their roles have swapped; Alexey is the shepherding co-chair, and Murray is the
Area Director.
