We are talking about Mail Integrity. It doesn't matter what is the 
reason for "middle ware" to make changes blindly and hope we can use 
NEAR PERFECT KLUDGES to secured the survivability of the mail integrity.

The only logical solution is an "authorized" resign.  Whether that is 
practical, thats a different mutated frog that one side doesn't want to 
touch.

The problem here is we are trying to make DKIM fit everywhere and it 
simply can't.
