Since the case of x!y@z is ambiguous, isn't the right thing to do to
bounce the letter, preferably with a message stating that the address is
ambiguous?  The fault can be attributed to whoever generated the address,
so why not just send it back?  This seems like the right thing to do; At
least the sender will *know* what happened to the letter, rather than
having it potentially get lost at a bad address.

Aren't there other ambiguous cases?  I can't think of any off the top of
my head, but what do people usually do with ambiguous addresses?
