No. I'm not in hotmail's administrative domain, gmail's administrative
domain, nor yahoo's administrative domain, etc. Yet my MUA can talk with
pop servers in all of them, and receive messages addressed to me in
those different administrative domains. Once those messages have been
transferred to my MUA, they've crossed an administrative domain boundary.

I see the use of A-R as no different from the use of POP and IMAP.
