What is it?
TLS reporting uses a DNS record at _smtp._tls to tell providers where to send delivery telemetry.
Why is it important?
Reports reveal downgrade attempts, certificate problems, and providers unable to deliver over TLS.
How do you improve it?
Publish a v=TLSRPTv1 record with a monitored mailto or HTTPS reporting destination.
