Free TLS reporting checker
Free TLS reporting checker and TLS-RPT lookup
Run a free TLS reporting checker to validate the live TLS-RPT DNS record for any domain, confirm report destinations, and review warnings before transport-security changes. Use it alongside MTA-STS when SMTP TLS visibility matters.
Primary use
TLS-RPT lookup
Fetch the live SMTP TLS reporting record instead of assuming report visibility is configured correctly.
Critical tag
rua destinations
Confirm where aggregate transport reports are meant to arrive before relying on them operationally.
Operational fit
Transport review
Use it with MTA-STS when transport policy and report visibility change together.
Output
Record + issues
Review the live TXT value, report endpoints, and any warnings in one troubleshooting view.

What this page returns
See the live TLS-RPT record
Confirm the public record instead of relying on an intended DNS change that may not be visible yet.
Verify report routes
Check whether the rua destination still points at the mailbox or workflow expected to receive transport reports.
Support transport rollout
Use TLS-RPT alongside MTA-STS so teams have both policy and visibility as transport posture changes.

Intent overview
What teams usually need from this tool page
The strongest tool pages answer the immediate question, make the next move obvious, and connect the free check to the broader MailSlurp workflow behind it.

Run a free lookup
Check the live TLS-RPT record for a domain
Enter the root domain. This checker validates the live TLS reporting TXT record, shows aggregate-report destinations, and surfaces warnings worth reviewing before the next transport change.
Product workflow
Take tls reporting checker and tls-rpt lookup beyond a one-off run
Use the free tool for the fast answer. Use the product workflow when the check needs history, owners, automation, and a place in your release or sender-health process.
Saved history
Keep every important run in one shared workflow
Use tls reporting checker and tls-rpt lookup as a repeatable checkpoint instead of relying on screenshots, scattered notes, or one person's memory.
Automation
Turn one-off checks into release and migration gates
Trigger the same verification from CI, internal tooling, or launch checklists so DNS, deliverability, and QA decisions stay consistent.
Ownership
Route failures to the right team before they become incidents
Move from ad hoc triage into shared operational visibility with alerting, escalation paths, and clearer accountability.
Next step
Move from a fast answer into a repeatable MailSlurp workflow
The free check is built for speed. The product path is where you save runs, automate verification, and give the right owner enough context to act before the next launch or incident review.
Recommended actions
Best fit
Use this when transport reporting needs a quick health check
TLS-RPT lookups are most useful after DNS changes, during MTA-STS rollout, and during security reviews when teams need to confirm report visibility before they trust the transport telemetry path.
- Validate report destinations after DNS updates
- Pair report visibility checks with MTA-STS rollout
- Give security and messaging teams one shared transport-report view
Upgrade path
Connect transport visibility to sender-domain operations
TLS-RPT is more valuable when transport checks sit beside MX, SPF, DKIM, and DMARC reviews in a repeatable sender-domain workflow.
- Review transport reporting and auth posture together
- Keep DNS and reporting drift visible across launch windows
- Shorten incident diagnosis when mail security posture changes
What this returns
A TLS reporting checker should answer visibility questions quickly
The value is not just whether a TXT record exists. It is whether the live record looks valid, whether report destinations are still correct, and whether the team can trust the transport-reporting path.
Record
Live TXT value
Review the exact TLS-RPT record visible in public DNS.
Reports
rua destinations
Confirm the aggregate report endpoints before relying on transport telemetry.
Warnings
Review notes
Catch malformed or weak setup details before transport reviews depend on them.
Workflow
MTA-STS pair
Use this with transport policy checks so discovery and visibility are reviewed together.
Operational use
Best used after DNS changes and during transport-security reviews
Searchers usually need TLS-RPT lookup because report visibility matters right now, not as a generic reference. Treat it as an operating step in transport and domain-health review.
After DNS edits
Re-run the lookup after changing TXT records so the team knows the correct report endpoints are publicly visible.
With MTA-STS rollout
Validate the reporting path alongside transport policy so security and messaging owners can see failures as the rollout progresses.
During transport review
Give the team one shared view of whether SMTP TLS reporting is still configured the way the operating model expects.
FAQ
Questions teams ask before they operationalize this workflow
What does a TLS reporting checker validate?
A TLS reporting checker validates the RFC 8460 TLS-RPT DNS record so you can confirm the version tag and report destinations used for SMTP TLS failure reporting.
Why use TLS-RPT if it does not enforce TLS by itself?
TLS-RPT adds visibility. It helps teams see when SMTP TLS delivery problems are happening so they can correct certificate, policy, or transport issues before they become recurring outages.
When should teams run a TLS reporting lookup?
Run it after DNS changes, alongside MTA-STS rollout, and whenever report visibility is part of the transport-security operating model.
What if the record is valid but no reports arrive?
That usually means the rua destination is not being monitored correctly, the mailbox route is broken, or transport issues are not occurring frequently enough to produce reports yet.
