For me, most RBLed sites are caught by list.dsbl.org. Some are from
dnsbl.njabl.org as well. As far as what spamcop catches is low because it's
lower on the chain.

I had a thing with management about a host that used verio and was blocked
by spews because they were in the same range as a well known spammer (and
from what I've read, verio is spammer friendly). One IP in a netblock
spamming and block the netblock isn't right. I don't use ANY rbl unless
they'll give information on a specific IP which states why it was added.

I can understand. But the way I see it, the spammers are a bigger problem
because they are the reason RBLs exist.

I don't use wirehub or whatever it is now because I couldn't get any
information on why an IP was listed. They always direct you to the same
static page for every blocked ip.

I don't really want to block solely on the fact you're a dialup user. I
have a mailserver on a dialup (static ip) and I don't want it blocked just
because someone has a hair up their ass about dialup users. However, if
there's so much spam seen from a user port (like some ISPs that have cable
or dsl connections), I will consider blocking those 'dialup' ranges.
