I do think there's room for some sort of "if you must do this bad thing, please 
do it this way" document series from IETF.
However, I don't think that would be applicable to having third party mail 
relays repair malformed messages.  I think that's no longer "best way to do 
something that has the potential to do harm" and closer to "how to make a bad 
situation worse".  
Of course, the devil is in the details.

I like that /much/ better than what I suggested.  Concise, accurate and 
appropriately apologetic.
