Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 9.10)
=====================================================================================

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.

Paravirtualization With Xen On CentOS 5.4 (x86_64)
==================================================

This tutorial provides step-by-step instructions on how to install Xen (version 3.0.3) on a CentOS 5.4 (x86_64) system. Xen lets you create guest operating systems (*nix operating systems like Linux and FreeBSD), so called "virtual machines" or domUs, under a host operating system (dom0). Using Xen you can separate your applications into different virtual machines that are totally independent from each other (e.g. a virtual machine for a mail server, a virtual machine for a high-traffic web site, another virtual machine that serves your customers' web sites, a virtual machine for DNS, etc.), but still use the same hardware. This saves money, and what is even more important, it's more secure. If the virtual machine of your DNS server gets hacked, it has no effect on your other virtual machines. Plus, you can move virtual machines from one Xen server to the next one.

How To Install VMware Server 1.0.x On An Ubuntu 9.10 Desktop
============================================================

This tutorial provides step-by-step instructions on how to install VMware Server 1.0.x (1.0.10 at the time of this writing) on an Ubuntu 9.10 desktop system. This is for those who prefer VMware Server 1.0.x over VMware Server 2.

Installing VirtualBox 3.1 On An Ubuntu 9.10 Desktop
===================================================

This tutorial shows how you can install Sun xVM VirtualBox 3.1 on an Ubuntu 9.10 desktop. With VirtualBox you can create and run guest operating systems ("virtual machines") such as Linux and Windows under a host operating system.

Virtual Mail And FTP Hosting With iRedMail And Pure-FTPd On Ubuntu 9.04
=======================================================================

iRedMail is a shell script that lets you quickly deploy a full-featured mail solution in less than 2 minutes. Since version 0.5, it supports CentOS 5.x, Debian 5.x, Ubuntu 8.04 and Ubuntu 9.04 (both i386 and x86_64). iRedMail supports both OpenLDAP and MySQL as backends for storing virtual domains and users. The OpenLDAP backend of iRedMail allows you to integrate all kinds of applications. This guide shows you how to integrate pure-ftpd into the iRedMail ldap backend on Ubuntu 9.04, passwords will be stored in ldap and you can change the password through webmail.

Virtual Hosting With Proftpd And MySQL (Incl. Quota) On Mandriva 2009.1
=======================================================================

This document describes how to install a Proftpd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine. In addition to that I will show the use of quota with this setup.

Virtual Hosting With PureFTPd And MySQL (Incl. Quota And Bandwidth Management) On Mandriva 2009.1
=================================================================================================

This document describes how to install a PureFTPd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine. In addition to that I will show the use of quota and upload/download bandwidth limits with this setup. Passwords will be stored encrypted as MD5 strings in the database.
