The provider reported the sending domain authenticated, a DMARC policy was present in public DNS, and the deployed service’s message was accepted by the mail provider. The check did not independently derive every DNS authentication record or measure inbox placement. It did not establish delivery to a subscriber list; subscriber fan-out and an unsubscribe route were absent in this record.",
