I'll take a deeper look into this (but I don't have enough time now).

I have the feeling that this is part of a larger problem which is how to inform a border 
SMTP gateway about caracteristics of final addresses in internal mail servers.

One example we were talking about is just what are the valid internal addresses which, 
with your needs for the consent framework, is a sub problem of the larger one.

For the problem of checking the validity of internal addresses (e.g.), there are many 
solutions, but none of them is perfect.

Maybe this problem could be taken out of your proposal and handled as a global one.
