Microsoft Windows XP Pro packages SMTP server software in its operating system. When you install Windows XP Pro, however, the SMTP services do not automatically install; these are optional components. You need your XP installation disk to install them.

Skill level:


  1. 1

    Click "Start." Select "All Programs" and click "Control Panel."

  2. 2

    Click "Add or Remove Programs." Click "Add/Remove Windows Components."

  3. 3

    Click "Application Server" and "Details." Click "Internet Information Services (IIS)" and click "Details."

  4. 4

    Click inside the check box next to "SMTP Service" to activate it. Leave all other defaults. Removing any checks will uninstall components that already exist on your computer. To see what an IIS option will install, highlight it and click the "Details" button.

  5. 5

    Click "OK" to begin installation of the IIS components. This activates certain services. If you have modified the services that run on your computer, for example, by disabling them, the installation won't complete correctly.

  1. 1

    Navigate to the Control Panel again. Click "Performance and Maintenance" and "Internet Information Services console." Right-click on the IIS option. Choose "Send To" and click to create a desktop shortcut. Double-click on the icon to start the IIS Control Panel.

  2. 2

    Right-click on the SMTP server and choose "Properties." Select the "General" tab and enter as your IP address.

  3. 3

    Click "Access." Find "Connection Control" toward the bottom. Click on "Connection." Click "Add" and enter "" again. Click "OK."

Tips and warnings

  • When setting up an e-mail client program like Outlook Express or Thunderbird, make sure that the SMTP protocol is localhost or
  • Most ISPs block port 25, the default port for outgoing e-mail. You may need to send your e-mail using a different port.
  • Check with your ISP or network administrator to ensure that setting up a local SMTP server does not violate their terms of use.
