JES was written and tested using Sun's 1.3 JDK on Windows XP. It should work on all OS's with JDK 1.3 or later. It may or may not run with previous JDKs.
JES can be installed as a Windows NT service. A batch file is included in the bin directory of this distribution. To install JES as a service, open the batch file and edit the properties to match your local system. You can then install and uninstall the sevice using the -install and -uninstall command line parameters. Once the system is installed, it will be started by default the next time the computer is restarted. To start the service the first time, you can type 'net start JavaEmailServer'.
