>> ISP mail servers that get used by spammers <<
 
Uhuh - so?  Which ISP is permitting/tolerating/mis-configuring their servers to be abused in that way?
 
I have seen very FEW spammers that MX mail from their "own" mail servers (as they would be shut down and/or blocked too easily). Nearly everyone is using proxies, open relays or otherwise hi-jacked machines - and the smaller once use consumer broadband accounts.

(sigh) Again I'm the voice of dissent... I find that CBL merits no higher than a weight of 5 out of my HOLD weight of 20.  I find that it includes a lot of ISP mail servers that get used by spammers.  They do seem to work at removing them, but meanwhile, it's throwing the baby out with the bath water.  I'm sure glad that Declude gives me a weighted system to work with.

Maybe it was just down on the day I tested it...

I like pure spamtrap RBL's because clean ones have no false positives.  CBL is a good one to add if you haven't checked it out, and it produces a lot of hits (with no FP's in a week of monitoring).

Maybe other "unlisted" entries reflect similar circumstances
(not available under normal circumstances)?
    

All of the DNSBLs (ip4r) and RHSBLs listed on the Declude spam databases
site (http://www.declude.com/Junkmail/support/ip4r.htm) are publicly
accessible, unless it has been noted otherwise in the comments (e.g., MAPS
tests).  The "SBBL" spam database can be access by using:

    SBBL    ip4r    sbbl.they.com    *    3    0

So far today I have flagged over 900 messages as spam using the SBBL test.
