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.}, }
