Unfortunately many so called business tiers are served from a dynamic block (or at least a dynamic block that is not flagged as business tier). In fact, many home tiers are allowed to run servers (I am one as an OptOnline BOOST user) yet are not served from an IP block that MAPS has flagged as allowed to run an MTA and thus relay messages to other MTAs or AoL.

Hey, I never said the list was accurate. :-|

Early on there were several dynamic block lists, but eventually they all gave up except for MAPS. It's just way too labor intensive to maintain. The ISPs are constantly moving things around, and most really aren't interested in giving third parties up-to-date information where their allocation ranges are. As a result, the main source for corrections on that kind of list are end user complaints.
