Understanding TLS-RPT
What is TLS-RPT?
TLS-RPT (TLS Reporting) is a standard for reporting TLS connection failures. It provides visibility into problems that prevent email from being delivered securely, helping you maintain reliable encrypted email delivery.
Benefits of TLS-RPT
Visibility
Get detailed reports on TLS connection failures, including which servers are affected and why.
Troubleshooting
Identify and fix certificate issues, cipher mismatches, and other TLS problems before they impact email delivery.
Security
Works hand-in-hand with MTA-STS to ensure encrypted email delivery and detect potential attacks.
Best Practices
- Use a dedicated mailbox for TLS reports to keep them organized
- Implement TLS-RPT alongside MTA-STS for comprehensive email security
- Review reports regularly to catch and fix issues early
- You can specify multiple email addresses for redundancy
