In version 3.1 and later of Mail Express, you can specify whether the default landing page (https://<hostname>) is the Internal portal, the Drop-Off portal, or user choice, which allows the user to choose which portal to use. The portals must be enabled before you can select them on this page.
To configure the default landing page
Launch the Mail Express Server administration interface. (e.g., click Start > Programs > Globalscape > Mail Express > Mail Express Admin or double-click the desktop shortcut).
Log in using the Mail Express Server administrator username and password that you specified during installation of the server.
In the navigation pane, click Portal Settings > General. The General Portal Settings page appears.
Under General Settings, specify the default landing page.
Internal portal: The Internal Web portal allows non-Outlook internal users to access Mail Express.
Drop-Off portal: Available to internal users, external users, or anonymous users.
User choice: A page appears on which the user clicks an icon to select either the Drop-Off Portal or the Internal Portal for that session.
Click Save to save the settings.
