Proxmox Mail Gateway 8.1 – Exciting New Features!

We’re excited to introduce the latest upgrade from Proxmox Server Solutions GmbH – Proxmox Mail Gateway 8.1. This new release heralds a significant leap forward for their open-source email security platform, designed to fortify organizations against a myriad of email threats including spam, viruses, Trojans, and phishing attempts.

A Closer Look at Proxmox Mail Gateway 8.1

Built on the sturdy foundations of Debian 12.5, Proxmox Mail Gateway 8.1 advances with a modern twist by adopting the newer Linux kernel 6.5. It also integrates ZFS 2.2.2 for robust file system management and PostgreSQL 15.6 for efficient database handling, ensuring a seamless and secure email management experience.

Key Features and Enhancements

  • Enhanced Rule System: The hallmark of Proxmox Mail Gateway has always been its comprehensive, object-oriented rule system. The latest iteration takes flexibility and control to new heights, introducing a “match-if” mode for more nuanced rule application and the ability to combine multiple objects in rules for tailored email filtering.
  • Advanced DKIM Signing: With cyber threats becoming more sophisticated, Proxmox Mail Gateway 8.1 steps up its game by offering advanced DKIM signing options. Now, the signing domain can be determined based on header information, allowing for stricter DMARC policy enforcement in sensitive environments.
  • Secure Boot Compatibility: Security is paramount, and with version 8.1, Proxmox Mail Gateway embraces Secure Boot. This ensures that only software verified by a valid digital signature can boot, offering an additional layer of protection against malicious attacks. A signed shim bootloader makes this possible, even in environments where Secure Boot is a mandatory requirement.
  • Web Interface Enhancements: Managing large email security deployments is now easier than ever, thanks to an improved web interface. A new filter and search box streamlines the process, allowing for efficient management of Relay Domains, Transport, Networks, and rule system Objects.

Further Innovations

Proxmox continues to refine its offerings, sharing a tweaked kernel across all its products, now rebranded to proxmox-kernel and proxmox-headers for consistency. Additionally, the latest version addresses SMTP smuggling, ensuring your email security is resilient against spoofing attacks at the SMTP protocol level.

Why Upgrade?

With its array of enhancements, Proxmox Mail Gateway 8.1 stands as a beacon of reliability and security in the realm of email management. Whether it’s the improved rule system, secure boot compatibility, or the streamlined web management interface, this release is designed to cater to the evolving needs of today’s organizations, ensuring that your email infrastructure remains both secure and efficient.
