MTA-STS/TLS-RPT Record Lookup

Mail Transfer Agent-Strict Transport Security (MTA-STS) is a protocol that makes it mandatory for any outgoing email from the domain to be TLS encrypted before being delivered to the recipient. Transport Layer Security Reporting is a protocol used alongside MTA-STS that enables the domain owner to receive reports with information on emails that failed to be delivered because the receiving server didn’t support TLS encryption.

Use this tool to lookup and validate your MTA-STS/TLS-RPT record.
