VPOP3 is administered through your web browser. You can access the administration settings by going to Start → Programs → VPOP3 → Configure VPOP3 in Windows on the PC where VPOP3 is installed, or by right-clicking on the VPOP3 status monitor icon in the task tray, and choosing VPOP3 Settings.
To access the VPOP3 settings from a machine other than the one VPOP3 is installed on enter
http://<ip.address.of.VPOP3>:5108 (e.g. http://192.168.1.1:5108)
in your web browser's address bar. You will need to log on using an administrator's username and password. Once you are logged on, click on the 'Administer' button on the WebMail menu.
