Reclassifying DMARC ARC as Historic

Quality: 9/10 Relevance: 9/10

Summary

This Internet-Draft proposes retiring ARC by reclassifying RFC 8617 as Historic. It reviews ARC’s findings, highlights operational lessons, and directs implementers toward DKIM2, arguing ARC is no longer worth deployment beyond intra-domain contexts and should not be relied upon for cross-domain email security or DMARC enforcement.
