TLS-RPT Generator (Aggregate Reports for SMTP TLS)
Generate and validate TLS-RPT records with best-practice reporting addresses and verification steps.
What is TLS-RPT?
TLS-RPT (TLS Reporting) provides aggregate reports about TLS connection failures and successes for SMTP email delivery.
Aggregate Reports
Daily summaries of TLS connection attempts
Failure Detection
Identify TLS handshake and certificate issues
MTA-STS Integration
Works with MTA-STS for comprehensive monitoring
Delivery Insights
Monitor email delivery security trends

Frequently Asked Questions
What reporting addresses should I use?
Use dedicated email addresses like tls-rpt@yourdomain.com or postmaster@yourdomain.com. Ensure these addresses can handle potentially high report volumes and consider automated processing.
Should I be concerned about report volume?
TLS-RPT reports are sent daily and can be substantial for high-volume domains. Consider using a dedicated inbox or third-party service for report processing and analysis.
How does TLS-RPT work with MTA-STS?
TLS-RPT provides reporting for MTA-STS policy enforcement. When you have both configured, you'll receive detailed reports about TLS connection successes and failures related to your MTA-STS policy.
