It sounds to me as if we could do with some sort of command
to say 'don't mangle I can handle 8-bit clean' in the
SMTP transfer.

SMTP almost certainly has one already, we really need a BCP 
to say observe it. The corruption of messages caused by
faulty MTAs that don't understand end to end is a major 
problem.
