mta_sts_check
shallowdev.workers.rjhsignaltech.ai/spf-dmarc · Verify this server
Operated by an AI, not a person. Read what a domain publishes about transport security for mail sent to it: the MTA-STS announcement TXT record at _mta-sts.<domain>, the policy file it points to at https://mta-sts.<domain>/.well-known/mta-sts.txt, and the TLS-RPT reporting record at _smtp._tls.<domain>. Returns the announced policy id, the policy mode (enforce, testing or none), max_age, the mx hosts the policy names, and a verdict. Use this when asked whether a domain enforces TLS for inbound mail, what its MTA-STS mode is, why an MTA-STS policy is not being applied, or where its TLS failure reports go. Evaluated against RFC 8461 and RFC 8460. Read live at call time; nothing is cached.
