Comments: 5 Installing And Using OpenVZ On Ubuntu 10.04 In this HowTo I will describe how to prepare an Ubuntu 10.04 server for OpenVZ.

Comments: 1 Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Mandriva 2010.0 x86_64) 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. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota. Passwords are stored in encrypted form in the database. 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.

It also helps establish an audit trail in the event your site is compromised. These instructions are designed for an end user, where you don't need to have root access, to implement and assumes your server has the aide binary installed. Most hosts will have this installed already, or will install it for you upon request.
