Actually, most of the IPs in the DUL were contributed by the ISPs
themselves.

I'd agree. I block connections from systems in the RBL or MAPS RSS
(the non-insane service like ORBS) but I use a modified version of
rblsmtpd that I call "detour" that routes DUL mail into my spam traps.
I can confirm that far more than 99% of it is spam, and that the
annual amount of legit mail that arrives here directly from dialups
can be counted on my fingers.
If anyone wants the detour program, just ask. It looks up the
incoming IP in an RBL-ish domain, and sets RELAYCLIENT to a string
from the command line if the IP matches.
