Transport reports
Check TLS-RPT
Check the TLS-RPT record, reporting URI syntax and DNS evidence.
Enter only the domain, such as example.com – without https://, a path or an email address.
A new check is available every 5 minutes per tool and domain. Until then, you see the saved result.
What the tool accesses
DNS.
How the check works
What exactly is checked?
- Query the TXT record under _smtp._tls through validating resolvers.
- Select exactly one TLSRPTv1 policy and check its syntax.
- Normalize rua destinations and show the published aggregate report recipients.
- Evaluate DNSSEC, resolver agreement, TTL and the expected report address.
Assessment
How is the result determined?
Passed means there is exactly one syntactically valid TLS-RPT record with a usable aggregate report recipient. The public check does not send a test report or contact a mailto address.
