Proxmox Mail Gateway 5.2

Download press release as PDF in English or German.

VIENNA, Austria – March 26, 2019 – Enterprise software developer Proxmox Server Solutions GmbH has released Proxmox Mail Gateway 5.2, the latest version of its open-source email security solution. The Mail Gateway is a complete operating system based on Debian Stretch 9.8 with a 4.15 kernel. The anti-spam and anti-virus filtering solution, available for over 14 years, 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.

Proxmox Mail Gateway 5.2 introduces a new mobile interface for the quarantine, making it very handy to check Delivery/Whitelist/Blacklist/Delete emails in the quarantine from any mobile device. The mobile interface is based on Framework7, a full featured open-source HTML framework for building Android and iOS apps.

The Proxmox Mail Gateway 5.2 release also introduces improvements in the LDAP integration, now allowing the use of Fully-Qualified Domain Names (FQDN) instead of IPs in the web user interface. Support for certificate verification (can be enabled for new deployments), and for LDAP+starttls has been added.

A new appliance template enables users to install the Proxmox Mail Gateway 5.2 as a privileged or unprivileged Linux Container. A new 'proxmox-mailgateway-container' Metapackage makes the installation of the template smaller and faster. As it does not depend on a kernel, it results in a reduced size and fewer updates.

The logging has been improved. The pmg-smtp-filter now logs each SpamAssassin rule’s score in addition to the rule names, therefore simplifying the analysis of the spam filter's performance without the need to access the email's source.

With improvements made to the TLS configuration of the web-based user interface, the pmgproxy can be configured via '/etc/default/pmgproxy' to disable or enable certain ciphers, compression, or cipher selection preferences.

Further improvements in Proxmox Mail Gateway 5.2 include:

  • The new command `pmg-system-report` provides an overview of the key characteristics of the setup and performance in Proxmox Mail Gateway, and improves the initial diagnosis for the Enterprise support.

  • With the .eml download from the quarantine interface (non-mobile) users can download the complete source of a quarantined message in .eml format for further analysis.

  • Improved handling of Blacklist/Whitelist in the Quarantine interface: a ‘multiselect’ option for removing multiple entries at once has been added.

  • Added support for custom checks: This functionality enables users to integrate their own custom check logic by providing a defined interface which can be enabled optionally, and runs a custom check before the email gets handed to the virus scanner and the rule system.

  • Proxmox Mail Gateway cluster now works with IPv6.

  • proxmox-spamassassin: Update the shipped rule sets.
