How this is measured
Tier 0. Read the rua= tag from the _dmarc TXT record already fetched for dmarc-policy. Where a destination mailbox sits on another domain, RFC 9990 requires that domain to publish <policy-domain>._report._dmarc.<destination> (or a * wildcard at the same name) before a conforming receiver will send anything. Denominator: domains that have a DMARC record — a domain with no policy has nothing to report on and is excluded rather than counted as receiving nothing.
Passive measurement: a single DNS lookup, TLS handshake, or homepage GET per domain. Aggregate-only; no individual company is named. 95% Wilson confidence intervals. Population: national company registries (Companies House, Brreg, SIRENE), sampled by size band and resolved to email-active domains. Parked domains excluded. Snapshot: brreg-norway-per600-seed20260730.

Why it matters
The reporting half of the p=none story, and the same shape: the record is valid, the checker is green, a reporting address is configured, and not one report has ever arrived. Without the feedback loop nobody ever learns which mail is failing, so the rollout from none to reject — the thing the policy exists to reach — never starts. unauthorised is the quieter of the two: the owner did everything visible correctly and the consent record is on a domain they may not control.
Limits of this measurement
Aggregate (rua) only; ruf uses the same consent mechanism but is rarely honoured and is not counted. Reporting is orthogonal to policy strength — a domain can enforce reject and still be blind, or sit at p=none and receive reports perfectly — so this is not a second reading of dmarc-policy. A destination that authorises the domain but silently drops the mail is indistinguishable from one that delivers it; consent is observable from outside, delivery is not.
