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.


   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.
