IETF Interim: Domain Keys Identified Mail (DKIM) 2026-04-29 20:00

Why It Matters

The decisions will shape DKIM2’s interoperability and deployability—keeping recipes and providing concrete error messages aims to simplify implementation and debugging, accelerating adoption of a next-generation email authentication standard.

Summary

At the IETF DKIM interim on April 29, chairs reviewed the updated DKIM2 draft, highlighting syntax changes (JSON-encoded recipes and base64 SMTP envelope parameters), a rewritten validation section with exemplar error messages, and cleanup of header-field definitions. A key open issue is whether to split out “recipes” into a separate document; authors and several implementers argue for keeping them together, citing working code and manageable implementation effort. The working group signaled a tentative consensus toward retaining recipes in the main spec but urged any objections to be raised promptly on the mailing list. Attendees also reported progress on implementations, including a lightweight XIM DKIM2 plugin, reinforcing feasibility.
