If memory serves me right this problem crops up with Courier MLM modifying a message when it is being redistributed. In that case, shouldn't the solution be that CourierMLM resigns the message as the origin of the distributed message? Other than that to my mind, you are going to end up chasing a never ending list of exceptions where something gets changed and DKIM breaks, and sticking plaster after sticking plaster to keep it working.
