Hi Jesse,

-> bhnc.njabl.org

This one is a bit safer, I have also seen false-positives with the one you 

In addition, dnsbl-1.uceprotect.net has also blocked IBM once, but you just
need to set the tolerances higher if using dnsbl-X.uce*.

cbl.abuseat.org also false positives occasionally

bl.spamcop.net & dnsbl.sorbs.net very accurate and result in few false 
positives (in my experience)

As far as the sophos blocker, I have not tried/used it.
