Installing the SMTP Server

This documentation assumes that you will be installing the email servers on a Windows 2000 Professional system. The same instructions will work for a Windows 2000 Server and for the most part the Windows NT 4.0 Server. The SMTP server for Windows NT 4.0 Server comes with the Option Pack. It's downloadable from Microsoft's Web site. The SMTP server is not available for Windows NT 4.0 Workstation.

Install the Microsoft SMTP server with Add/Remove Programs. You need administrative privileges for this operation. Go to Control Panel > Add Remove Programs, click the Add/Remove Windows Components, Select the Internet Information Services (IIS), click the Details button and look for SMTP. Make sure it's checked and click the OK, Next and Finish buttons to finish up.

To check that it installed, go to the START button > Programs > Administrative Tools and select Internet Information Services. If you can't find it there, try START > Settings > Control Panel. Look in Administrative Tools fot Internet Information Services. There should be a single computer listed and in this case, the Default Web Site and we just added the Default SMTP Virtual Server. If you expand the Default SMTP Virtual Server there are two items. Domains and Current Sessions. When you click on the Domain, the default local Fully Qualified Domain Name (FQDN) of this computer should be shown in the right pane.

Installing the POP3 Services

You can place POP3S.EXE and POPAgent.EXE anywhere, but to keep it simple put them along with IMS.CPL and IMSCMN.DLL in the %systemroot% directory. This usually is C:\WINNT\System32. After copying the files, open the Control Panel. You should see the EMWAC IMS applet in the list.

You need administrator rights to install the POP3 server and the POPAgent. Both of these are services. They must be installed. They will not run from the command line or by double clicking them. Open the Command Prompt and navigate to the C:\WinNT\System32 directory. Type:

C:\WINNT\System32>POP3S -install

The system should respond with a dialog stating the service installed successfully. If not check the trouble shooting section. Do the same for the POPAgent service. Type:

C:\WINNT\System32>POPAgent -install

You should get the same response. Open the Services applet from the Control Panel. The two services should be listed. The POP3S service should be listed as IMS POP3 Server. Right click on it and make sure the Startup type: is Automatic. If it's not started, click the Start button to start it. Click OK. The next time the system starts, it will start by itself. Do the same for the POPAgent service. It should show up as IMS POP Agent

That's all there is to it. You can carry on to the configuration. I also have enclosed three scenarios to show how the whole thing works in practice.
