No TLS reporting configured
MINORWhat it means
Without a TLS-RPT record. Nobody tells you when delivery to example.com fails on TLS. That is the feedback you need before turning MTA-STS from testing to enforce, without it you are enforcing blind.
How to fix it
Publish a TXT record at _smtp._tls.example.com: v=TLSRPTv1; rua=mailto:tlsrpt@example.com
Check your own domain
This page describes the condition. To find out whether your domain has it, run the TLSRPT test or the full checkup, which examines every record at once.
Understand it properly
This page covers one condition. For the whole picture, TLS-RPT, defined, or start at the Health Library.
Where this comes from
We judge this against RFC 8460 section 3. Every finding on this site cites the specification behind it so you can check the work rather than take our word for it.
Other TLSRPT conditions
TLSRPT_MISSING
Every fix on this site is yours to implement. If you would rather someone did it, I take this work directly.
