Which would be resolved in exactly the same way in which mails that already loop is solved (i.e too many hops). (Assuming you don't rewrite <>. You could also add a header to indicate a forwaded email. X-ForwardedFor: <original-return-path> and use that for a bounce). Either way existing forwarding is broken.
