This is pretty much how I see it, too - except that it's impossible in general for the software to know how to find the user's "local" mailbox. So it's not reliable as a deliverable address. This was really frustrating when trying to cancel a message sent from a 100-machine workstation cluster, and only being able to do so from the exact same machine, despite the fact that they all shared the same filesystem image and MX host. :-(
