I always wonder why SMTP-RFC didn't do it differently. Always use normal sender/recipient information, but for 'bounce' messages use "ERROR"-command instead of DATA. And if on "ERROR" makes another "ERROR", don't send it to avoid loops. Besides this functionality "ERROR" would work like DATA. Too simple?
