This tutorial shows how to prepare a Debian Lenny (Debian 5.0) server for the installation of ISPConfig 3, and how to install ISPConfig 3. ISPConfig 3 is a webhosting control panel that allows you to configure the following services through a web browser: Apache web server, Postfix mail server, MySQL, BIND nameserver, PureFTPd, SpamAssassin, ClamAV, and many more. This tutorials differs from "The Perfect Server - Debian Lenny (Debian 5.0) With MyDNS & Courier [ISPConfig 3]" in that I use BIND and Dovecot here instead of MyDNS and Courier (of course, the other two variants - BIND & Courier or MyDNS & Dovecot are possible as well).
