Check TLS reporting

Available

Ready to inspect the published TLS reporting declaration.

What this check does

Deliverlens queries the _smtp._tls TXT records for the supplied domain and identifies a supported TLSRPTv1 declaration.

How to read your result

The report describes the published declaration. Report delivery, destination authorization and how other senders use it remain unverified.

What to do next

Compare the reporting destination with your monitoring provider’s instructions and review incoming reports for transport failures.

Common questions

Does this check send a report?

It reads the public declaration. Report delivery requires observations from participating sending systems.

Is TLS reporting optional?

Yes. Interpret an absent record in the context of your transport monitoring requirements.
