Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 10.04)

Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 10.04)

This document describes how to install a mail server based on Postfix
that is based on virtual users and domains, i.e. users and domains that
are in a MySQL database. I’ll also demonstrate the installation and
configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier
can authenticate against the same MySQL database Postfix uses.
