Measurement estimates from a single vantage point — not a compliance certification. Guidance below is for operators, not an SLA.

DMARC
p=reject
p=reject — published organizational policy. Strongest published policy (SPF/DKIM alignment still not measured here).
Meaning: Published DMARC policy at _dmarc.douane.gouv.fr (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.
Record at _dmarc.douane.gouv.fr:
v=DMARC1; p=reject; rua=mailto:dmarc@douane.finances.gouv.fr
Policy publication only — SPF/DKIM not measured. Not part of the 0–4 row score.
