I have a feeling that you are doubling up here. As someone else said, 
the SORBS-DUL is a dialup list and Zen also contains a dialup block 
list, I dont know if the NJABL list still contains the dynablock list 
but that became the PBL list which is part of Zen.

Personally, I use a single carefully selected block list at the MTA 
layer (which I can selectively whitelist if ever necessary) and the rest 
are used in SA. I found using them in MS a tad restrictive.

My advice; use block lists with care.
