Do you guys know of a way to schedule, or automate the movement of older messages from one folder to another? I'd like to be able to setup a rule that automatically executes something like "move any message older than N days in folder x to folder y". I don't think there's a simple way to do that through the UI, but if there is, I sure could use it. If there's no simple way to do that in the UI, is there a way to do it through the backend - i.e. via cron executing some zcs command?
