Well, I'm finally fed up with using the "Free single user" trimmed down version of Proxmox Email Gateway. I did some looking around and came across MailCleaner.
It looks promising thus far (still doing the install). Its Debian based, users RAZR, SpamAssassin ClamAV and other goodies. It's an opensource project, and seems to be exactly what I'm lookin for. FREE.
A few items of interest in regards to MailCleaner (That can be found HERE in their installation doc.)
setup keyboard layout: By default, the Mailcleaner automatic installation CD configures your server with a Swiss French (fr_CH-latin1) keyboard.
So we have to change the default keyboard lay out for us Americans.
cp /usr/share/keymaps/i386/qwerty/us.kmap.gz /etc/console/boottime.kmap.gz
From the command line should do the trick for you.
Next run the MailCleaner installation
/root/mailcleaner_install.sh
And last steps are configure your IP address and hostname
/root/bin/ip_configurator
