Proxmox, known for developing the Proxmox Virtual Environment distribution kit for deploying virtual server infrastructures, introduced the release of the Proxmox Mail Gateway 5.2 distributive. Proxmox Mail Gateway is presented as a turnkey solution for quickly creating a system for controlling email traffic and protecting the internal mail server.

An installation ISO image is available for free download. Distribution-specific components are under the AGPLv3 license. To install updates, you can use both a paid Enterprise repository and two free repositories that differ in the level of stabilization of updates. The system part of the distribution is based on a package based on Debian 9.8 (Stretch) and the Linux kernel 4.15. Proxmox Mail Gateway components can be installed on top of existing Debian 9 servers.

Proxmox Mail Gateway functions as a proxy server, acting as a gateway between the external network and an internal mail server based on MS Exchange, Lotus Domino or Postfix. It is possible to manage all incoming and outgoing mail flow. All correspondence logs are sorted out and available for analysis via a web interface. Both graphs are provided to assess the overall dynamics, as well as various reports and forms for obtaining information about specific letters and delivery status. Cluster configurations are supported for high availability (maintaining a synchronized backup server, data is synchronized via an SSH tunnel) or load balancing.

In open access, a beta version of the NGINX Unit 1.3 application server was released. Developers continued to expand the ability to run web applications in Python, PHP, Perl, Ruby and Go. The project code is written in C and is distributed under the Apache 2.0 license.

Features

Version 1.3 eliminates the problems with handling errors when installing HTTP connections.

Among other changes:

  • parameter max_body_size to limit the size of the body of the request;
  • new parameters for setting timeouts when setting up an HTTP connection:
         "settings": {
              "http": {
                  "header_read_timeout": 30,
                  "body_read_timeout": 30,
                  "send_timeout": 30,
                  "idle_timeout": 180,
                  "max_body_size": 8388608
              }
          },
  • automatic use of the Bundler where possible in the Ruby module;
  • http.Flusher interface in the module for the Go language;
  • The possibility of using characters in the UTF-8 encoding in the request headers.

The first version of the NGINX 1.1 application server was released in mid-April 2018. Under the control of NGINX Unit, several applications can be executed simultaneously in different programming languages, the startup parameters of which can be changed dynamically without the need to edit the configuration files and restart.
