This tutorial will help you to install and set up a few email accounts, by using the built-in POP3 Service in Windows Server 2003. I will assume you have basic knowledge about the Windows Server family and Mail Servers, but I have tried to make this tutorial as easily comprehensible as possible. The tutorial has been tested on Windows Server 2003 Enterprise Edition but should also work on Windows Server 2003 Standard Edition. I will not cover MX records and other similar things in this release.
To follow this tutorial you need a stand alone server. You can of course use a Domain Controller, but that assumes you understand when to not follow the tutorial and use other settings (i.e. authentication method).
