Mine are adapted from a previous post by /dev/rob0:

postscreen_dnsbl_threshold = 3
postscreen_dnsbl_sites = 
 zen.spamhaus.org*3 
 b.barracudacentral.org*3
 dnsbl.njabl.org*2 
 bl.spameatingmonkey.net*2 
 bl.spamcop.net
 dnsbl.ahbl.org 
 spamtrap.trblspam.com 
 swl.spamhaus.org*-5
 list.dnswl.org=127.[0..255].[0..255].0*-2
 list.dnswl.org=127.[0..255].[0..255].1*-4
 list.dnswl.org=127.[0..255].[0..255].[2..255]*-6

And FWIW, the below statistics correspond to a recent 24hr period; TOTAL
is the number of IPs listed by a given zone, and UNIQ is the number of
IPs listed *only* by that zone.  Regarding overlap with whitelists, I've
noticed that it's consistently highest for spamtrap.trblspam.com.

    UNIQ/TOTAL   DNSBL                    DNSWL
