The impetus behind this limit was to catch badly-behaved hosts that
(1) loop DSNs, adding an extra MIME layer at each iteration, and (2)
delete Received: headers so normal mail loop detection fails.  Yes, we
have seen this in real life.

So if you use a limit, I would set it very high (500 or 1000, say).
