Dear DMARC WG, Now that RFC7489 has been published, there remains several unresolved problems this WG is charted to resolve, primarily-- 1. Addressing the issues with indirect mail flows
These are reviewed by https://tools.ietf.org/html/draft-dmarc-interoperability-00 https://tools.ietf.org/html/draft-otis-dmarc-author-align-01 was written to highlight possible solutions. John Levine's recommendation that mailing-list operators take on the costly burden of having their participants change their providers is not practical. Based upon the almost complete lack of interest of bulk email providers at promoting a solution, it seems the path forward is to define a new non-aligned header field able to retain the author role information, otherwise the From is likely overwritten as the only practical means of ensuring message acceptance in the face of provider DMARC (ab)use. By defining a new header field, this should reduce disparity in where to find the author role than that caused by current ad hoc solutions. Such a definition would also better avoid downgrading 'reject' into 'quarantine'. Any thoughts?
