With dbox, have you considered having one collection of dbox files per namespace, rather than one collection of dbox files per mailbox/folder, and then use indexes to track which emails belong to each mailbox/folder?  This would drastically speed up copying between folders, because you'd just update the index rather than writing the copied email to a new dbox file.

Just a thought.
