To get near the same catch rate I had to enable njabl.org, list.dsbl.org, 
bl.spamcop.net and cbl.abuseat.org.
I had njabl already but before zen.spamhaus.org, but it catches very little, 
and I have the cbl list at the end to hopefully lower my query rate. You will 
want to make sure that if you add cbl to your MTA, you remove it from 
spamassassin, because this is what I think made my lookups go over the allowed 
rate.
Spamassassin doesn't query the zen list, but queries the sublists sbl, xbl, 
and cbl. That would probably triple your lookups on each message. There is 
chatter on the spamassassin lists that they will be disabling the spamhaus 
lookups by default in a future version.

If you want to add others, or see how these perform, you can look at your 
hitrates in spamassassin. The above had better than 99% spam rates in my 
system with very little ham, and the ham was actually spam that scored too low 
to be caught that way. But as with anything YMMV.
