Proxmox Mail Gateway 9.0 delivers a powerful, open-source email security solution designed to intercept threats before they ever reach your internal mail server. Acting as a protective shield positioned between your firewall and mail system, this platform provides robust anti-spam and antivirus filtering to defend organizations against a wide array of email-based dangers, including sophisticated phishing attempts, malware, and trojans.
The foundation of this new release is Debian 13 “Trixie”, bringing a host of underlying improvements. This updated core includes more recent software packages, enhanced hardware compatibility, and fortified security measures. Version 9.0 also adopts Linux kernel 6.14 as its stable default, offering users better performance and broader system compatibility from the moment of installation. Furthermore, the platform is now equipped with the newest releases of essential security tools: ClamAV 1.4.3 and SpamAssassin 4.0.2.
A significant usability upgrade comes in the form of a completely redesigned quarantine interface. Built using the modern Yew framework, this new interface is not only faster but is also optimized for use on mobile devices like smartphones and tablets, making it simpler for administrators to manage blocked messages from anywhere.
Authentication capabilities have been substantially expanded for greater flexibility. OpenID Connect realms can now be fully configured directly through the web interface. This enhancement includes support for claim mappings and the ability to assign default roles to users who are provisioned automatically, streamlining integration with popular identity and access management systems and simplifying single sign-on (SSO) deployments.
On the security front, the filtering engine has been sharpened. The Content-Type filtering mechanism has received updates to recognize new MIME type definitions associated with Microsoft executables. This ensures that high-risk file types are consistently and reliably identified and blocked, preventing them from ever reaching an end-user’s inbox.
Proxmox Mail Gateway 9.0 is available for immediate download. The comprehensive ISO image can be installed on physical hardware using a straightforward installation wizard. For existing users, upgrading from version 8.2 to 9.0 is a supported process, with a detailed migration guide provided. The software can also be installed on a standard Debian system or deployed as a container appliance within a Proxmox Virtual Environment.
