TLS-RPT (RFC 8460) delivers daily JSON reports about TLS connection problems and MTA-STS/DANE failures for your mail domain. The record is a TXT at _smtp._tls.<domain> and pairs naturally with MTA-STS or DANE.

Email addresses and/or HTTPS endpoints, comma-separated; , ! ; inside URIs are percent-encoded automatically.
