If names other than the default names are entered for the trash or sent items folder when setting up the Mail Server via the GO!NotifyLink Administrative Web console (Server Administration > Mail Servers > Edit Mail Server), the folder(s) will be created in users' accounts and any mail sent or deleted from the GO!NotifyLink connected device will populate the folders.  

Default trash and sent items folder names are listed in the GO!NLES Administration Guide.

Exceptions:
This is not the case for Kerio and FirstClass collaboration suites.  For Kerio or FirstClass, these folders are not created automatically.  Consequently, items sent from the NotifyLink device are sent successfully, but they are not tracked in a folder and items deleted from the device will not be successfully deleted from the server until the appropriate trash folder is created.
