Proxmox Mail Gateway 7.1
VIENNA, Austria – November 30, 2021 – Enterprise software developer Proxmox Server Solutions GmbH ("Proxmox" or the "Company") has today released Proxmox Mail Gateway 7.1, the latest version of its open-source email security solution. The Mail Gateway is a complete operating system based on Debian Bullseye 11.1, but using a newer Linux kernel 5.13, and OpenZFS 2.1.
The anti-spam and anti-virus filtering solution, available since 2005, functions as a full-featured mail proxy, that is deployed between the firewall and the internal mail server. It protects organizations against threats, such as spam, viruses, Trojans, and phishing emails. As one of the few open-source enterprise email filtering solutions available, Proxmox Mail Gateway continually provides updates to current versions of its underlying Linux distribution, helping companies to stay safe and up-to-date in a security sensitive domain.
What’s new in Version 7.1
Proxmox ships the latest upstream release of Apache SpamAssassin 3.4.6 with an updated rule-set for its Mail Gateway. PostgreSQL 13.5 is also included.
- This release brings enhancements to the API. Support for IP configuration via DHCP has been added. While email still needs working DNS records, users can now manage and configure the IP for Proxmox Mail Gateway in the DHCP configuration. When adding a new entry to a ‘Who’ object, a duplicate check is performed before saving. Proxmox Mail Gateway uses the first search domain from /etc/resolv.conf as domain name - Version 7.1 can now also handle entries in domain names that have a trailing dot. Finally, support for delivery status notifications (DSN, RFC 3461) has been made available in before-queue filtering mode and improved for after-queue filtering.
- Improved web interface: The configuration of LDAP backends via GUI has been improved. Changes can now be applied without specifying a password. Furthermore, the APT repository configuration, which was restricted to 'root', is now visible and editable by all users with 'Administrator' privileges. Some translations have been updated including Arabic, Basque, Brazilian Portuguese, French, German, Simplified Chinese, Traditional Chinese, and Turkish.
- Multi-Factor Authentication for the GUI: Multiple second factors can now be configured for a single account. Web Authentication (WebAuthn), the general standard for authentication, one-time recovery keys and Time-based OATH (TOTP) are all available as second factors.
Proxmox Mail Gateway is released under the GNU Affero GPL, v3. The downloadable ISO image can be installed on bare-metal or a VM. The ISO contains an installation wizard that automatically installs and configures all the necessary components on the host. This eliminates the need for manual configuration later. The ISO contains the complete feature-set and can be downloaded at https://www.proxmox.com/downloads
Additionally, you can install Proxmox Mail Gateway as a container appliance inside Proxmox Virtual Environment.
For enterprise users, Proxmox Server Solutions GmbH offers a subscription-based support model, which provides access to the extensively tested Enterprise Repository, as well as technical support. Subscription prices start at EUR 139 per host, per year, for unlimited users and domains. The Enterprise Repository provides regular updates via the web interface, and is recommended for production use.
