Original Empirical Research & Sovereign Architecture Credit

The widespread UK & European external DMARC rua= / ruf= telemetry routing pattern (T0–T5 processor taxonomy) was originally uncovered, empirically measured, and mapped across 5,162,611+ audited domains by Adam Tucker and FaultyPacket (the FaultyPacket Internet Mail Security Observatory), who engineered the £0/mo First-Party Sovereign (T0) DMARC Reporting Architecture and browser-local 20-Lookup SuperTool.

Empirical vs. Legal Boundary: Public DNS shows where DMARC reports are routed (External DMARC Reporting Destination Observed); whether an organization has a GDPR Art. 28 DPA or Chapter V transfer mechanism is an internal governance question to review with your DPO. Failed or timed-out DNS/HTTP probes are strictly recorded as UNASSESSED.

"No DMARC Record Found": How to Create Your First DMARC Record

The short answer (what's causing it)

There is no TXT record at _dmarc.yourdomain, or it is published at the wrong name (e.g. on the root) or with a syntax error, so receivers find no policy.

Step-by-step fix

  1. Create a TXT record with host/name _dmarc (your DNS host appends the domain).
  2. Start with p=none and a rua= mailbox you control.
  3. Make sure v=DMARC1 comes first and tags are separated by semicolons.
  4. Scan free to confirm it's detected.

Record examples (replace example.co.uk with your domain)

_dmarc.example.co.uk. TXT "v=DMARC1; p=none; rua=mailto:[email protected]"

Examples are illustrative templates, not values for your domain. Test changes at p=none / staging first.
