If it is forwarding as implemented by Exim, the loop gets broken when
the maximum number of Received: headers is reached.

If it is "forwarding" by creating a new message each time, the loop will
break if the size increases and there is a limit. But hey, if you want
to attack servers this way you can just write a program that spits out
mail. You don't have to be so elaborate.
