I don't understand the IMAP settings for Sent Items and Trash. The
VersaMail manual says:

Sent Folder - Shows the name of your Sent Mail folder on the server
Trash Folder - Stores deleted emial in the folder you specify on the server
Server Folder Synchronization - To synchronize a server folder, click in the
Synchronize column to the right of the folder name to select Yes.

I chose to synchronize the server folders but I didn't change the names of
the folders on the server because I'm not sure what that means. The
synchronization keeps failing. Can someone explain how these should be set
up? Thanks.
