I'm using paid spamhaus RBL (local zone file rsynched) for a very long \
time, at work, and we are very happy about it. I use complementary RBL also \
like fresh.spameatingmonkey.net for reject_rhsbl_sender, \
reject_rhsbl_client and reject_rhsbl_reverse_client and \
b.barracudacentral.org. I've had false positives with \
b.barracudacentral.org so I've had to add a permit clause to whitelist \
clients before the b.barracudacentral.org reject.

For a month I've tested Abusix configured just after Spamhaus: it catched \
many spams that Spamhaus wouldn't block, including a cutting edge phishing \
campaign. It's a very effective RBL, but it's pricey too. They are open to \
negotiation though. I might replace Spamhaus with Abusix someday.
