For SPAM I believe that an integration between a SPAM filter and a local 
handled DNS map is the best way. You filter mail with SPAM filter and you 
keep track of the originating IPs. Then you add some heuristic scripts 
that feed you local DNS map that you use inside CustMapsList, using the 
data generated by the SPAM filter.
