What's everyone using for DNSBL's these days?
Currently I use (in this order in Postfix):
cbl.abuseat.org
b.barracudacentral.org
zen.spamhaus.org
dnsbl-1.uceprotect.net

UCEProtect has also been good. I used to use SORBS, but were a pain to deal with at times, so I haven't used them for a while. Other peoples mileage may vary

…UCEProtect?

Sorry, my own inside joke. http://uceprotect.org/
@Erasmus Darwin:
Zen.spamhaus.org includes xbl.spamhaus.org which, in turn, includes cbl.abuseat.org. So you should be able to drop cbl.abuseat.org from your checks without any loss in coverage.
Didn't know that, I'll try it out thanks!
Of the dnslists I use in Exim, zen.spamhaus.org picks up the most for me by far - 97% - of the mail rejected. Barracuda picks up about 2% although I get timeouts on occasion. psbl.surriel.com accounts for the other 1%. I've tried bl.spamcop.net, bl.mailspike.net and some others. Spamcop caught very few. Mailspike was interesting. It would catch a lot then stop and then catch a lot again. Guess it has to do with the nature of it. I did get a few false positives so I removed it. Removing spamcop and mailspike didn't seem to make any difference ultimately. I get very few (less than 3 a day) that are spam. I could tighten up my rules a bit but I've got one client who must subscribe to every legitimate department store that sends horrendous html e-mails. They trigger all kinds of spamassassin rules. I am in the process of whitelisting those now so we'll see what I can do with SA.
