Check a domain's MTA-STS setup (RFC 8461): the _mta-sts record, the HTTPS policy file with certificate check and no redirects, mode, max_age and whether every MX host is covered, plus the TLS-RPT record (RFC 8460). Use when an agent must tell whether inbound mail is protected against TLS downgrade, or why senders report MTA-STS failures for a domain.
