Do you mean "xbl.spamhaus.org" if so according to
Declude's list "...This contains the same data as the CBL test..."
From 05/01/04 on our server has processed 183721
messages.
In this time range CBL has helped to catch 54948 spam
messages by having also a false positive result for 481 legit
messages.
In the same time range XBL has helped to catch 52163 spam
messages by having also a false positive result for 68 legit
messages.
So if I don't miss something it's not exactly the
same.
