A. Windows 2003 includes a POP3 service that lets users receive and store messages for later retrieval. Coupled with the SMTP service, you can create a basic mail system using only Windows 2003's built-in functionality. To install the POP3 service, which also automatically installs the SMTP service, perform the following steps:

  1. Start the Control Panel Add/Remove Programs applet.
  2. Click Add/Remove Windows Components.
  3. After the Windows Components Wizard appears, select Applications Server and click Details.
  4. Select E-mail Services, then click Next (you can also click Details to install the optional Web administration element).

Windows 2003 will copy the files required (you might be prompted to insert the installation CD-ROM) and configure the service.
