We analyzed DMARC report emails from the last 3 days across nearly 3,500 reporting organisations. Looking only at organisations that sent a substantial volume of reports during that period, just 9 were fully RFC compliant (GMX, WEB.DE & mail.com), while most major reporting organisations had at least one compliance issue.

The most common problems were surprisingly basic: missing required fields like "version", "envelope_from", and SPF "scope", invalid attachment filenames and media types, empty "<sp/>" elements, and invalid values like "sampled_out", "unknown", "hardfail", and even "Pass" with a capital P.

Some large providers scored well but still had edge case issues. Comcast, Microsoft, and Fastmail were close, but not perfect.

Others performed far worse. Yahoo, Google, Amazon SES, and Mimecast all generated large volumes of non-compliant reports.

At DMARC scale, small XML mistakes create real interoperability problems. They break parsers, cause data loss, and force receiving platforms to build endless workarounds.

We’ve already contacted several organisations and shared examples of the issues we found. The goal is better interoperability across the email ecosystem. Until then, DMARC platforms like URIports will keep doing their unofficial second job: translating creative interpretations of the RFC into something that actually parses 😄

DMARC reports IETF RFC compliance

After analyzing millions of DMARC reports, I came to the disappointing conclusion that only a fraction of them comply with the DMARC IETF RFC guidelines. Most of them lack mandatory elements or hold incorrect element values.

Helping a novice set up a domain with NameCheap and Google Workspace has been an enlightening experience. It's hard to fathom how much base knowledge of the inner workings of the internet is required. How are SMBs that have no IT staff expected to keep up? Neither vendor was particularly helpful. #DNS #SPF #DKIM #DMARC

Checking one of my domains, I see the expected results with one exception - DKIM - which your scan shows as ❌ when it really should be ✔️. Since "Full reports are coming soon", the discrepancy remains a mystery.
