What is TLS-RPT?
TLS-RPT is a security standard (RFC 8460) that enables LetsDMARC to receive JSON-formatted reports regarding email encryption failures. It acts as an "early warning" system, identifying failed STARTTLS handshakes or misconfigurations that prevent secure email delivery, often used alongside MTA-STS to detect malicious attacks.
From this page you can create the TLS-RPT record to be published on the DNS.
