There is no one-size-fits-all, so do what fits at your site. What some folks do is weigh barracuda*1 and a few other dnsbl's such as bl.spamcop.net, bl.spameatingmonkey.net, fresh.spameatingmonkey.net, hostkarma.junkemailfilter.com=127.0.0.2, or ix.dnsbl.manitu.net, all scored at one. That way multiple less-trusted dnsbl's must list a site to reject their mail. Opinions on which dnsbls are safe to block on their own vary greatly. Adjust the postscreen scores as you see fit.
Thanks Noel, and everyone else for your feedback. Nick
