However, using that feature will have a rather nasty side effect of not letting legitimate users know that their mail has not been delivered. And at least here in Germany, knowingly not delivering mail is illegal; although these mails cannot be delivered, I suppose you may be liable to let the sender know (at least if it is a human ;-)
