CommuniGate Pro users can connect to the CommuniGate Pro Server with any Web browser (via the HTTP protocol) to manage their Accounts, to browse their Mailboxes, to read, copy, delete, forward, and redirect messages, to move messages between Mailboxes, to compose and submit new messages, etc.
This CommuniGate Pro component is called the WebUser Interface.
Registered users and guests can also use this component to browse Mailing List archives.
By default, the HTTP User module accepts clear text TCP/IP connections on the TCP port 8100, and the secure connections - on the TCP port 9100. If your Server does not have to coexist with some other Web Server on the same computer, it is recommended to change these port numbers to 80 and 443 - the standard HTTP and HTTPS port numbers.
In this case your users will not have to specify the port number in their browsers.
