So giving a 550 response to a mail with a forged sender doesn't help anyone much, because the smarthost is then responsible for delivering the bounce, which it cannot. If this becomes a problem, maybe the ISP's smarthost shouldn't be accepting mail that doesn't appear to come from an email account provided by the ISP.
