VIENNA, Austria – November 30, 2022 – Enterprise software developer Proxmox Server Solutions, the company behind Proxmox Mail Gateway, announces today point release 7.2 of its open-source email security solution. Proxmox Mail Gateway, available since 2005, is one of few enterprise-grade open-source email filtering solutions. It protects organizations against threats such as spam, viruses, Trojans, and phishing emails and functions as a fully-featured mail proxy that is deployed between the firewall and the internal mail server.

Enhancements in Proxmox Mail Gateway 7.2

  • Proxmox Mail Gateway 7.2 is a complete operating system based on Debian 11.5 (“Bullseye”), using the newer Linux kernel 5.15, as well as ZFS 2.1.6. The Proxmox developers ship the latest upstream release of Apache SpamAssassin 3.4.6 with an updated rule-set for its Mail Gateway. PostgreSQL 13.8 is also included.
  • Enhancements in the rule system: With the comprehensive object-oriented rule system of Proxmox Mail Gateway, users can create customized rules for their mail environment. This version improves the handling of international emails by adding support for Unicode characters and better handles SMTPUTF8 emails.
  • The Quarantine interface brings improved usability for administrators and end-users alike:
    • In the administrator view, the admin can now select multiple emails, the ‘Receiver’ information is displayed, and there is a context menu in the mail-listing, for the ‘Attachment’ and ‘Virus’ quarantines.
    • The SpamAssassin rules can now be visually sorted by scores in the SpamInfo grid, thus helping to accelerate the decision on which ones to select and remove. The 'Deliver' and 'Delete' actions are now colorized, improving intuitive handling of common actions.
    • By additionally displaying attachments in the ‘Spam’ and ‘Virus’ quarantine, administrators get a more complete overview of the email in question.
    • ‘Virus’ and ‘Attachment’ quarantine can now optionally be filtered by ‘Receiver’ – a function especially helpful in larger deployments.
    • The Proxmox Offline Mirror tool allows keeping Proxmox Mail Gateway nodes – with restricted or without access to the public internet – up-to-date and running. With the ‘proxmox-offline-mirror’ utility, it is possible to manage a local apt mirror for all package updates for Proxmox and Debian projects. From that mirror, users can create an external medium (USB flash drive or a local network share) and can then update their policy-restricted or air-gapped systems. For subscribers with a Premium or Standard subscription level, Proxmox offers an offline subscription key for its product portfolio.
