It enables senders to report and verify the success of TLS connections, offering a global view of email security. This presentation at FOSDEM 2025 highlights how TLSRPT can be configured in Postfix, marking a pivotal shift for open-source MTAs to enhance security transparency. **Implementation in Postfix** Postfix will be the first open-source MTA to incorporate TLSRPT, allowing for the collection and reporting of TLS security data. This development results from collaboration between Wietse Venema and sys4, aiming to promote secure email practices. The open-source C-library created for this purpose is available on GitHub, encouraging other MTAs to adopt TLSRPT capabilities. **Benefits and Challenges** The session underscores the benefits of TLSRPT in identifying and resolving TLS failures, thus maintaining secure communications. It also addresses challenges such as the need for broader adoption and potential technical hurdles in implementation. The open-source nature of this project invites community participation to overcome these barriers. **Future Prospects** The talk concludes with prospects for further development and monitoring of TLSRPT reports, emphasizing the role of community feedback and collaboration. The upcoming Postfix release will support additional security standards, reflecting ongoing efforts to enhance secure email transport. ## Importance for an eco-social transformation TLSRPT's integration into open-source platforms like Postfix is crucial for eco-social transformation, as it democratizes access to robust email security tools, enhancing privacy and trust in digital communications. This development empowers smaller organizations and community projects to maintain secure communication channels without relying on proprietary solutions. For eco-social designers, the open-source C-library and reporting service offer tools to build secure communication infrastructures. However, challenges remain in ensuring widespread adoption and overcoming technical and policy-related hurdles. Encouraging collaboration and sharing best practices within the open-source community can address these issues and promote a more inclusive digital ecosystem. ## Links [Video recording (AV1/WebM)](https://video.fosdem.org/2025/k4601/fosdem-2025-5776-tlsrpt-comes-to-open-source.av1.webm) [Video recording (MP4)](https://video.fosdem.org/2025/k4601/fosdem-2025-5776-tlsrpt-comes-to-open-source.av1.mp4)
