Proxmox Mail Gateway is presented is a solution turnkey to quickly create a system to monitor mail traffic and protect the internal mail server. Works as a proxy server which acts as a gateway between the external network and the internal mail server based on MS Exchange, Lotus Domino or Postfix. All incoming and outgoing mail correspondence flows can be managed.
Proxmox Mail Gateway is implemented between the firewall and the internal mail server and protects organizations against spam, viruses, Trojans, and phishing emails. All correspondence records are disassembled and available for analysis through the web interface.
Both charts are provided to the user to assess the overall dynamics, as well as various reports and forms for information on specific letters and delivery status.
While cluster configurations are supported for high availability (keeping a backup server in sync, data is synced via SSH tunnel) or load balancing.
Besides that, A complete set of tools is provided to provide protection, filter spam, phishing and viruses.
ClamAV and Google's Safe Browsing Database are used to block malicious attachments and a suite of SpamAssassin-based anti-spam measures are offered, including support for reverse sender verification, SPF, DNSBL, gray lists , Bayesian classification system and URI-based blocking of spam.
Main new features of Proxmox Mail Gateway 6.1
In this new edition of Proxmox Mail Gateway it is highlighted that the distribution syncs with the Debian 10.2 base, while on the part of Linux kernel has been updated to version 5.3, taken from Ubuntu 19.10.
On the part of the system we can find the addition of support for DKIM digital signature generation (DomainKeys Identified Mail) for outgoing emails. It provides a web interface that allows the inclusion of DKIM only for individual domains to configure the use of DKI.
In addition, it is also highlighted that it has been added a new system to quarantine remote attachmentsFor example, after a virus or malware scan has been triggered. Instead of deleting, these attachments can now be delayed along with the letters for further analysis by the admin.
Another novelty that stands out in the ad is a web interface for setting weights of various spam filtering criteria in SpamAssassin. Weight changes are possible at the individual rule level, allowing you to tailor the antispam system to the details of the current environment. You can also selectively disable the rules that result in false positives.
Has been added an experimental filtering mode at the SMTP session stage before putting a message on the queue ("Before queue"). This mode is incompatible with the Monitoring Center.
As well Improved handling of configurations and rules in cluster environments is highlighted. The filter engine is now informed about changed settings that require a configuration reset, reducing the number of situations that require a manual reset pmg-smtp-filter. Change notifications are transmitted during the cluster synchronization process.
