TLS-RPT

Reporting channel that surfaces failed TLS negotiations to your inbound mail servers, so transport problems are seen rather than silently tolerated.

Capabilities

What we implement

  • Reporting address and record configuration
  • Report parsing and trend review
  • Correlation with MTA-STS policy state
  • Alerting on repeated negotiation failures

Security

How it is hardened

  • Early detection of interception or misconfigured senders
  • Evidence trail for transport-security assurance
  • Reports routed to a monitored mailbox, not a black hole

Architecture

TLS reporting loop

Sending servers report failed TLS negotiations to an address you control, turning silent transport failures into visible data.

  1. 01 · Declaration

    _smtp._tls TXT recordReporting addressAggregation window

    Reports arrive daily from participating senders.

  2. 02 · Collection

    Reports land somewhere a human or tool actually reviews.

  3. 03 · Analysis

    Repeated failures usually point at expiry, name mismatch or a broken relay.

  4. 04 · Action

FAQ

TLS-RPT questions we are asked

Is TLS-RPT worth it without MTA-STS?
It is useful either way, but the pair belongs together: MTA-STS states the requirement and TLS-RPT tells you when senders could not meet it.
How many reports should we expect?
A handful a day for a typical domain, mostly from large providers. Volume is small enough for a dedicated mailbox.
Do reports contain message content?
No. They describe connection and certificate outcomes in aggregate, not messages.
