Comments: 32 Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 9.04) 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. 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. 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.

Comments: 0 Running Vhosts Under Separate UIDs/GIDs With Apache2 mpm-itk On Ubuntu 9.04 This article explains how you can install and configure apache2-mpm-itk on an Ubuntu 9.04 server. apache2-mpm-itk is an MPM (Multi-Processing Module) for the Apache 2 web server. mpm-itk allows you to run each of your vhost under a separate UID and GID - in short, the scripts and configuration files for one vhost no longer have to be readable for all the other vhosts. mpm-itk works with mod_php because mpm-itk is based on the traditional prefork MPM, which means it's non-threaded. This means you don't need to use suExec or suPHP anymore to run a website's PHP scripts as a separate user.
