Mail security generator

Create the SMTP TLS reporting record.

Build a TLSRPTv1 TXT value for _smtp._tls so supporting senders know where to deliver aggregate SMTP TLS failure reports.

What it answers

Use the result to make the next technical decision.

TLS-RPT gives domain owners aggregate visibility into certificate, policy and connection failures encountered by senders attempting TLS-protected delivery.

Limits

Read observations in context.

Publishing a reporting address does not enforce TLS. Pair TLS-RPT with an appropriate transport policy and protect the report mailbox from unnecessary exposure.

Privacy

Marketing analytics never receive the target.

DotMoose records only the tool name and a coarse success/error outcome for marketing analytics. Active server diagnostics use bounded operational security logs without placing the entered domain, IP, URL, DNS answer or report contents into marketing telemetry.
