So unfortunately, I've been tasked with setting up an Ubuntu server to send and receive email (amongst other things). My friend is hosting the Ubuntu VM on his box, but has only done limited setup.

HowtoForge – This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database.

This is weird, when i do a apt-get install postfix .... dpkg goes thru configuring and tries to add a user and group. <BR><BR>So it asks for a password two times (why, wtf, im root already)<BR> ...
