Proxmox Mail Gateway in container
The Proxmox Mail Gateway template is an OpenVZ OS template that allows you to run the Antispam & Antivirus Mail Gateway. Proxmox runs in different virtualization environments but in OpenVZ it is almost twice as fast as on the virtualization solutions from the market leader - due to the minimal overhead in OpenVZ.

Prerequisites
I assume you have already a running OpenVZ server. This HowTo is based on an fresh Centos 4.4 installation with OpenVZ kernel 2.6.9 but should work also with all other combinations. I used a Dual Xeon with 2 GB Ram.
Installation
Download the Proxmox OpenVZ template
wget http://www.proxmox.com/cms_proxmox/cms/upload/bittorrent/debian-3.1-proxmox-mailgateway.tar.gz
Copy the template into the template cache, usually to /vz/templates/cache/
Create a default config
Create a reasonable default config if you don’t have one. The following command creates the file /etc/vz/conf/ve-default.conf-sample which contains reasonable defaults if you plan to run 5 VEs:
vzsplit -n 5 -f default
Create the VPS
Choose a free VPS ID, we use 777 inside this guide and
vzctl create 777 --ostemplate debian-3.1-proxmox-mailgateway --config default
Configure the VPS
Set IP Address and DNS nameservers, start servers automatically at boot time: please adapt these settings to your enviroment
vzctl set 777 --onboot yes --ipadd 192.168.2.110 --nameserver 192.168.2.100 --nameserver 192.168.2.101 --hostname proxmox --searchdomain yourdomain.tld --save
Set guaranteed memory to 512MB, maximum disk space to 4GB
vzctl set 777 --vmguarpages 131072:2147483647 --diskspace 4000000:4400000 --save
And finally set the root password:
vzctl set 777 --userpasswd root:YOURPASSWORT
Start the VPS
vzctl start 777
Now you have a running Proxmox! By typing vzlist you should have something like this.
[root@vz1 ~]# vzlist
VEID NPROC STATUS IP_ADDR HOSTNAME
777 56 running 192.168.2.110 proxmox
[root@vz1 ~]#
