TLS-RPT Checker
Ensure your TLS-RPT records are properly configured to receive TLS delivery reports.
TLS-RPT Checker
Query and validate SMTP TLS Reporting (TLS-RPT) records to ensure you receive diagnostic reports about email delivery failures due to TLS issues.
Enter a domain above to audit its SMTP TLS reporting configuration.
What is TLS-RPT?
SMTP TLS Reporting (TLS-RPT) allows domain owners to request reports about the success or failure of TLS-encrypted emails delivered to their domain. It is often used in conjunction with MTA-STS and DANE.
How it works
You create a TXT record at _smtp._tls.yourdomain.com. This record tells sending mail servers where to send daily reports regarding TLS connection successes and failures. These reports are usually delivered in JSON format, often compressed as GZIP or ZIP.
Common TLS-RPT Tags
- v: Protocol version (must be `TLSRPTv1`).
- rua: Reporting URI(s) where reports should be sent. This can be a `mailto:` address or an `https:` URL. Multiple URIs can be separated by commas.
