Exim 4.99-RC3 has been released for testing, representing a significant step toward the official launch of Exim 4.99. This release candidate focuses on bug fixes and introduces several new features, including sieve inbox options for redirect routers, a "connection_id" variable for better tracking of email connections, and enhanced logging capabilities. Notably, it includes improvements in handling IPv6 addresses within MySQL and PgSQL lookups.
The build process has been optimized, allowing developers to exclude certain features like JSON and LDAP lookups to streamline the compiled binary. New variables for managing DMARC compliance have also been added, alongside expanded options for manual-route routers and SMTP transports. Additionally, support for SRV records indicating TLS availability has been implemented.
Security enhancements are a priority in this release candidate, addressing vulnerabilities such as CVE-2025-26794 and CVE-2025-30232. Numerous bug fixes have also been included, such as those related to hintsdb support using SQLite3, issues with the SPA authenticator, and DKIM signing process crashes.
The Exim development team encourages users to thoroughly test RC3 and provide feedback to ensure a smooth transition to the official release. Users can download RC3 either as a tarball or by cloning the Git repository.
In extending the discussion, the ongoing development of Exim highlights the importance of community feedback in refining software before official releases. As email protocols evolve and security threats become more sophisticated, the enhancements in Exim 4.99-RC3 reflect a proactive approach to maintaining robust email services. Future updates may focus on integrating even more advanced features, improving performance, and ensuring compliance with emerging standards in email security and delivery
