IETF Last Call Review of draft-ietf-dmarc-failure-reporting-20
review-ietf-dmarc-failure-reporting-20-opsdir-lc-wicinski-2025-11-28-00

Hi,

I have been selected as the Operational Directorate (opsdir) reviewer for this
Internet-Draft.

The Operational Directorate reviews all operational and management-related
Internet-Drafts to ensure alignment with operational best practices and that
adequate operational considerations are covered.

A complete set of _"Guidelines for Considering Operations and Management in
IETF Specifications"_ can be found at
https://datatracker.ietf.org/doc/draft-opsarea-rfc5706bis/.

While these comments are primarily for the Operations and Management Area
Directors (Ops ADs), the authors should consider them alongside other feedback
received.

**Document**: draft-ietf-dmarc-failure-reporting

**Reviewer**: Tim Wicinski

**Review Date**: 2025-11-28

**Intended Status**: Standards Track

## **Summary**

This document describes "failure reports," which provide details about
individual messages that failed to authenticate according to the DMARC
mechanism.

The document is ready with some minor nits.

The IDNits that Marco Tiloca raised in the ARTART review need to  be addressed:
https://datatracker.ietf.org/doc/review-ietf-dmarc-failure-reporting-20-artart-lc-tiloca-2025-11-26/

The document describes the operational mechanisms, however, in order to deploy
the failure reports requires reading of draft-ietf-dmarc-dmarcbis, but both
portions are well written.

## **Minor Issues**

## Terminology

The Terminology section references DMARC-bis document, which is useful.  But
there are a number of definitions in "Reporting Format Update" section that
mentions looking in RFC6591.  I would suggest you also add this reference to
the Terminology Section.

## **Nits**

Optional editorial suggestions (e.g., acronym expansions or grammar fixes).

- **Example**:

 > *Abstract*: Expand "NFV" on first use.

 > Section 3.1: "it’s" -> "its".*
