TLS-RPT (RFC 8460) allows domain owners to receive reports about TLS negotiation failures when remote servers attempt to deliver email to their domain.
A TLS-RPT record is published as a DNS TXT record at _smtp._tls.yourdomain.com and specifies where sending mail servers should deliver TLS failure reports.
