We will create an imaginary company with the name OrganicBrownSugar that has a class C network with the IP address 192.10.1.0.

Please note that this sample configuration is suitable only for a network not connected to the internet. If you want to connect this server to the internet additional steps have to be taken that are not covered in this document. This procedure however is a good basis for any further steps you might want to take later.

The base for this Linux Server will be RedHat 7.0, the current version of the Redhat Distribution as of this writing. I choose Redhat for several reasons:

1.

Probably the most popular Linux distribution

2.

a lot of literature is available for Redhat

3.

an website with extensive resources is available at www.redhat.com

4.

commercial support is available from Redhat

5.

one of the most used distributions focused on server installations

6.

The Redhat Package Manager for easy installations

Redhat 7 comes with 2 CDs, both of which are needed for the installation. This document does not cover details about Linux or the installation process itself, it just guides you through the installation, setup and configuration process of the various components. If you are new to Linux we recommend reading a quick introduction at http://www.netikus.net/documents/winnt-to-linux.pdf. If you are experiencing problems during installation and configuration of your Linux system, please refer to one of the resources available at one of the following websites:

http://www.redhat.com/
http://www.linuxdoc.org/

I tried to make this guide as "safe" as possible. About 95% of the commands that have to be typed are listed in an extra line. However, sometimes – especially towards the end –explanations are given to perform a specific standard task.

This document is accompanied by the zipfile Linux-Mailserver-Installation.zip that is available in the downloads section of www.netikus.net. It includes the tar.gz files and some configuration files as well. You might want to check the distributors homepages for the most current version of their applications. The included versions, however, where tested and used while writing this document.
