When I did my research for setting up RBL's, I found old comparisons

spamcop lists had slightly higher levels of flase postives.
stop spreading FUD. if you know of false positives, show us so that we
see what you exactly mean.
It's difficult to find current data. The original document I found,
somewhere among old spamassassin wiki/forum files, was a decent comparison
of the percentage FP's and FN's for many blocklists, but do you think I
can find it now? :)
I found *some* stats at http://stats.dnsbl.com which would seem to
suggest that the spamcop database is now very accurate. Though I am
somewhat hesitant to use spamcop as our own servers once had a brief
listing with them (and it wasn't due to spam). Even so their stats
all seem to be at least a year old?
Still hoping to find something more recent and detailed....
I think I will upgrade from using sbl-xbl to using 'zen' at the MTA level,
as it seems to be universally recommended....
