Validate TLS Reporting (TLS-RPT)
Enter your domain to instantly verify your TLS-RPT DNS record. Ensure you are successfully receiving JSON reports about inbound SMTP encryption failures and MTA-STS validations.
Real-Time TLS-RPT Syntax & SMTP Failure Diagnostics
Gain critical visibility into inbound email encryption failures in real-time. We execute direct, encrypted DNS over HTTPS (DoH) queries to instantly validate your TLS Reporting (TLS-RPT) configuration, strictly parsing v=TLSRPTv1 syntax and deeply evaluating rua= URI schemes for exact RFC compliance and deliverability. Guaranteeing absolute technical accuracy with strictly real-time operations and zero simulated data, our backend completely bypasses local caches to audit your _smtp._tls TXT records, ensuring your MTA-STS companion protocols are flawlessly monitoring for certificate errors and Man-in-the-Middle downgrade attacks.
