Well, the point it that that it doesn't currently. Yes, you're correct on the
first one, but our LMTP recipients aren't public email addresses, so the LMTP
recipient isn't the "final" email address, but the address prior to that
(internal aliasing on the MTA and inserted as a different header). It's a
many-to-one mapping so it couldn't just be aliased back the other way by the MTA
using a reverse path, either.
