- with some lists, you want to check the IPs found in the Received headers (and X-Originating-IP...) if spam passes through an MTA listed in SBL, then it's probably spam. - some lists are not usable for outright blocking. they give a reputation score which can be used with other factors (spam signs). - some people use fetchmail or the like. They can't use the MTA to block such mail.
