How this is measured

Tier 0. TXT at _smtp._tls.<domain> for v=TLSRPTv1. Denominator: has_mx.

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: domains sampled from the Common Crawl web graph, filtered to those that do email. Parked domains excluded. Snapshot: common-crawl-domain-stratified-c400-g2500-seed20260729.

Why it matters

Without TLS-RPT, a domain has no way to learn that mail to it is being delivered in the clear or that its MTA-STS policy is failing. It is the feedback loop that makes the other two enforceable rather than aspirational.

Limits of this measurement

Low severity and near-universally absent, so it is reported as context on adoption maturity rather than as an urgent defect.
