Maybe, maybe not.

I cannot explain much about MAPS these days without going into 
hypotheses about the mental stability of some of my former 
co-workers, but I think that in fact there is a consistent mapping of 
originating list to DNS response in the RBL+ and that if you are a 
paying customer they will probably be willing to define that for you. 
I cannot find any mention of the specifics on the MAPS website, but 
that's no big surprise: the website has many outdated parts and MAPS 
has not taken its maintenance seriously for many months.
