TLS-RPT Checker
Check whether your domain publishes a TLS-RPT record, which asks other servers to send you reports when they fail to deliver to you over TLS.

This tool reads your domain's public _smtp._tls TXT record at the moment of the check. Results reflect current public DNS and can be affected by caching and propagation (up to 24-48 hours). Guidance is general and not a substitute for your provider's official instructions. We don't store the domains you check.What is TLS-RPT?
TLS-RPT asks other mail servers to send you reports whenever they can't deliver to your domain over a secure TLS connection - the monitoring half that pairs with MTA-STS's enforcement.
How to set it up
Publish a TXT record at _smtp._tls.yourdomain: v=TLSRPTv1; rua=mailto:you@yourdomain.
Why it matters
Without TLS-RPT you have no visibility into silent TLS delivery failures. With it, you learn when senders can't reach you securely so you can fix it early.
