As others have pointed out, these are safe if you canonicalize to FQDMs before you
call the resolver.  Carl says that these are ugly in received mail, and I agree.
But I have stuff in my Mlocal's final rewrites to rip everything out that does not
need to be there -- which includes not only the domain name but the host name as
well, since we have the same aliases everywhere.

So I can leave this in.  Others may want to consider the same approach.
