Proxmox Mail Gateway 8.0 releases

Proxmox Mail Gateway is the leading open-source email security solution protecting your mail server against all email threats the moment they emerge. Organizations of any size can easily implement and deploy the comprehensive anti-spam and anti-virus platform in a few minutes. Deploying the full featured mail proxy between the firewall and an internal mail server allows to control all incoming and outgoing email traffic from the single web-based interface. Proxmox filters the whole email traffic at the gateway before it reaches the mail server and protects businesses against email attacks and other malicious threats. Proxmox Mail Gateway is open-source software, licensed under the GNU AGPL, v3. Commercial support subscriptions are available from Proxmox.

Proxmox Mail Gateway

The Mail Gateway is a complete operating system based on Debian Stretch 9.5 with a 4.15 kernel. The anti-spam and anti-virus filtering solution functions like a full-featured mail proxy deployed between the firewall and the internal mail server and protects organizations against spam, viruses, Trojans, and phishing emails.

Changelog v8.0

The anti-spam and anti-virus filtering solution is a complete operating system now based on Debian 12 (“Bookworm”), but defaulting to a modern Linux kernel 6.2, and includes ZFS 2.1.12, and PostgreSQL 15.3. For users of Proxmox Mail Gateway 7.3 a detailed upgrade documentation is available, helping to enable a smooth upgrade. Additionally, a pre-flight checking script helps to identify potential misconfigurations before the upgrade.

With this major release 8.0, the Proxmox development team adds a new text-based UI (TUI) mode for the installation ISO. The TUI is written in Rust, using the Cursive library. With the new TUI mode, issues with launching the GTK based graphical installer, sometimes observed on both very new and rather old hardware, can be eliminated.

The default settings in many areas of this version have been optimized, reflecting the various deployment possibilities seen among Proxmox Mail Gateway users. This further enhances the out-of-the-box experience and spam detection rates for new users.
