Thanks for the pruning tips Ralf. I figured some of those were dead,
just hadn't bothered to do any verification recently.

FWIW, here's my dnsbl config:
reject_rbl_client zen.spamhaus.org,
reject_rbl_client dul.dnsbl.sorbs.net,
reject_rbl_client dsn.rfc-ignorant.org,
That's wrong.
reject_rbl_sender dsn.rfc-ignorant.org
reject_rbl_client bl.spamcop.net,
reject_rbl_client relays.mail-abuse.org,
Dead, Jim
reject_rbl_client korea.services.net,
reject_rbl_client web.dnsbl.sorbs.net,
reject_rbl_client relays.bl.gweep.ca,
reject_rbl_client proxy.block.transip.nl,
I *think* this one may be dead as well.
reject_rbl_client relays.dnsbl.sorbs.net
The only 2 that catch anything regularly, for me, are spamhaus and
sorbs. The 2nd of these usually only catches stuff when there's a
transient lookup failure to zen. The korea one stopped two spam in the
last year AFAICT. I may as well remove the others...
I have more success today with the standard postfix DNS and hostname
checks and an IP block list than with dnsbls. Recent partial pflogsumm
output summary:
Client host rejected: Access denied (total: 231)
cannot find your hostname (total: 97)
Helo command rejected: need fully-qualified hostname (total: 37)
blocked using zen.spamhaus.org (total: 57)
blocked using dul.dnsbl.sorbs.net (total: 4)
YMMV.
P.S. I'd look into uribl and implementing your own ban list before
either of the two dnsbls you mentioned.

Presenting using the following blacklists...

These do a good job for me, but I wanted to look for opinions on a
couple additional ones. Specifically look for false-positive opinions,
adding additional DNS lookups isn't much concern to me.
The two I am looking at are ...

I will give the list developer credit for the fact he/she has done
research. However, the list developer has not provided any evidence as
to the results or validity of using this list (even when asked for).
Not to mention, I have not found anywhere on the site where it lists any
price for mass-querying or any data feed service for its zone files. We
purchase data feed service for SpamHaus and query an average of close to
four(4) million every 24 hours.
combined.rbl.msrbl.net
Don't know much about this list. Perhaps someone else has feedback.
