Abstract

DMARC [RFC7489] introduces a mechanism for expressing domain-level policies and preferences for message validation, disposition, and reporting. The DMARC mechanism, especially when employed with restrictive policies, encounters several different types of interoperability issues due to third-party message sourcing, message transformation, or rerouting. In particular, DMARC with restrictive policies causes problems for many Mailing Lists.

   Interoperability Issues between Domain-based Message Authentication,       Reporting, and Conformance (DMARC) and Indirect Email Flows

Abstract

   Domain-based Message Authentication, Reporting, and Conformance    (DMARC) introduces a mechanism for expressing domain-level policies    and preferences for email message validation, disposition, and    reporting.  However, the DMARC mechanism enables potentially    disruptive interoperability issues when messages do not flow directly    from the author's administrative domain to the final Recipients.    Collectively, these email flows are referred to as "indirect email    flows".  This document describes these interoperability issues and    presents possible methods for addressing them.
