The second DMARC WG milestone will see the publication of a document describing DMARC interoperability issues with indirect email flows plus possible methods to address issues.
The WG produced draft-ietf-dmarc-interoperability. The rest of this document describes proposed methods to address specific interoperability issues.
This listing mirrors the table of contents from the interoperability document. Issues are annotated with links to proposed solutions/methods, as proposed solutions/methods can address more than one issue.
Add ARC details here.
The X-Original-From header is being used in various contexts. This page attempts to capture how this header is being used, starting how it is used today to how it is being used to deal with DMARC-related issues.
See various proposals:
DKIM conditional signatures, draft-levine-dkim-conditional
Third party authorization, draft-otis-tpa-label
Mentioned in some early drafts.
