What is Proxmox Mail Gateway?

E-mail security begins at the gateway by controlling all incoming and outgoing e-mail messages. Proxmox Mail Gateway addresses the full spectrum of unwanted e-mail traffic, focusing spam and virus detection. Proxmox Mail Gateway provides a powerful and affordable server solution to eliminate spam, viruses and blocking undesirable content from your e-mail system. All products are self-installing and can be used without deep knowledge of Linux.

Proxmox

 Processing of incoming e-mail traffic

Planning for Deployment

Easy integration into existing e-mail server architecture

In this sample configuration, your e-mail traffic (SMTP) arrives on the firewall and will be directly forwarded to your e-mail server.

Infrastructure without Proxmox Mail Gateway


Using the Proxmox solution all your e-mail traffic is forwarded to the Proxmox Mail Gateway, which filters the whole e-mail traffic and removes unwanted e-mails. You can manage incoming and outgoing mail traffic.

Filtering Outgoing E-mails Many e-mail filter solutions do not scan outgoing mails. Opposed to that Proxmox Mail Gateway is designed to scan both incoming and outgoing e-mails. This has two major advantages:

  1. Proxmox is able to detect viruses sent from an internal host. In many countries you are liable for not sending viruses to other people. Proxmox outgoing e-mail scanning feature is an additional protection to avoid that.
  2. Proxmox can gather statistics about outgoing e-mails too. Statistics about incoming e-mails looks nice, but they are quite useless. Consider two users, user-1 receives 10 e-mails from news portals and wrote 1 e-mail to a person you never heard from. While user-2 receives 5 e-mails from a customer and sent 5 e-mails back. Which user do you consider more active? I am sure its user-2, because he communicates with your customers. Proxmox advanced address statistics can show you this important information. Solution which does not scan outgoing e-mail can‟t do that.
