I'll let you two fight this one out :}
The point was that Exim got TRY_AGAIN for looking up only some of the
addresses- shouldn't it return TRY_AGAIN to the upper level iff it
gets it or a failure for *all* addresses? This is taking the view that
looking up "A foo.com" and looking up "AAAA foo.com" is just like
looking up two different addresses...
