The PERCENT test was never to catch spam as I recall. IMAIL, and other mail servers for that matter, can be made to relay by sending a piggybacked %address via a trusted backup server. Since this test is still used by many of the open relay testers then failing it can get one blacklisted as an open relay. Interestingly I have seen only one attempt by a spammer to use this method on our servers but I see 2 or 3 open relay tests per month. As an example you might have 2 IMAIL servers backing up each other or you might have a MS SMTP server as a backup MX in your list of accepted IP's to an IMAIL server. In either case it may be possible to relay using the %piggyback address.
