The EMWAC Internet Mail Services are configured through the EMWAC IMS Control Panel Applet (IMS.CPL).
The applet displays several "tabbed dialogs":
Directories
Logging
Misc
Lists
Aliases
When you have finished making changes to the configuration, click on the OK button. The configuration will take effect the next time you start the affected services. If the services are already running, you must stop and restart them. (The exception to this is mailing lists and aliases. If you've changed the membership of a mailing list or aliases, the change will be recognised immediately.)
The configuration information is stored in the Windows NT Registry. If you understand the function and structure of the Registry, you may wish to read documentation on IMS use of the Registry.
