Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 8.04 LTS)

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. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota (quota is not built into Postfix by default, I'll show how to patch your Postfix appropriately). Passwords are stored in encrypted
form in the database (most documents I found were dealing with plain
text passwords which is a security risk). In addition to that, this
tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.
