Indeed, this is why adding another level of complexity to an already byzantine system is pernicious. Why would I want to exert effort declaring what mail I do and don't want to receive through Outbox, then wait a substantial amount of time to receive the mail that is of value to me? If anything, simply handling my own mail is the most effectual and expedient option. The mail that I want gets retrieved and dealt with by me, and the mail that is irrelevant to me can be thrown away with trivial ease. Why would I subject myself to another level of complexity that entails extra effort on my part, an added delay, and an expenditure? The service is fixing a non-issue, if not exacerbating a real one.
