By using the {pmg}, all your e-mail traffic is forwarded to the
-Proxmox Mail Gateway, which filters the whole e-mail traffic and
+Proxmox Mail Gateway, which filters the 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 {pmg} is designed to scan both incoming and outgoing
-e-mails. This has two major advantages:

-----------------
-In order to pass e-mail traffic to the {pmg} you need to allow traffic
-on the SMTP the port. Our servers use the Network Time Protocol (NTP)
-for time synchronization, RAZOR, DNS, SSH, HTTP and port 8006 for the web
-based management interface.

System Requirements
-------------------
-{pmg} needs dedicated server hardware but can also run inside a
-virtual machine on any of the following plattforms:
+The {pmg} can run on dedicated server hardware or inside a virtual machine on
+any of the following platforms:
* Proxmox VE (KVM)
* KVM (virtio drivers are integrated, great performance)
-* Virtual box™
+* VirtualBox™
-* Citrix XenServer™
+* Citrix Hypervisor™ (former XenServer™)
-Please see http://www.proxmox.com for details.
+* LXC container
+
+* and others supporting Debian Linux as guest OS
+
+Please see https://www.proxmox.com for details.
In order to get a benchmark from your hardware, just run 'pmgperf'
after installation.
* bootable CD-ROM-drive or USB boot support
-* 1024x768 capable VGA/Monitor for Installer
+* Monitor with a resolution of 1024x768 for the installation
-* Hard disk 8 GB - ATA/SATA/SCSI/NVME
+* Hard disk with at least 8 GB of disk space
-* Ethernet Network interface card
+* Ethernet network interface card
Recommended System Requirements
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-* Multicore CPU: 64bit (Intel EMT64 or AMD64)
+* Multicore CPU: 64bit (Intel EMT64 or AMD64), +
+ for use as virtual machine activate Intel VT/AMD-V CPU flag
* 4 GB RAM
* bootable CD-ROM-drive or USB boot support
-* 1024x768 capable VGA/Monitor for Installer
+* Monitor with a resolution of 1024x768 for the installation
+
+* 1 Gbps Ethernet network interface card
+
+* Storage: at least 8 GB free disk space, best setup with redundancy,
+ use hardware RAID controller with battery backed write cache (``BBU'') or
+ ZFS. ZFS is not compatible with a hardware RAID controller. For best
+ performance use Enterprise class SSD with power loss protection.
+
-* 1 GBps Ethernet Network interface card
+Supported web browsers for accessing the web interface
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-* Hardware RAID1 or RAID10, Raid Controllers need write cache with
- batteries backup module for best performance
+To use the web interface you need a modern browser, this includes:
-* Enterprise class SSD with power loss protection (e.g. Intel SSD DC
- 35xx/36xx/37xx)
+* Firefox, a release from the current year, or the latest Extended
+Support Release
