Quite frankly, I'd prefer to stay on Roy's side which consists in saying
that when a compliant message is passed to an intermediary, the output is
a compliant message, and when a non-compliant message is passed, the
output is indetermined.

Otherwise we'll have to document all possible corner cases, which will
result in even worse implementations givent that we won't be exhaustive.

Probably that all the trouble comes from the obligations made to senders,
with senders sometimes being intermediaries. I've been bothered by this
in the past. So the point above at least would solve the issue for them :
they have to emit clean things but if they forward stupid things, well,
it's the other side's fault.

Regards,
Willy
