I have to agree with LuKreme, my overnight had 446 blocked prior to RBL,
and only 387 by RBL. Again, noted that 'Barracuda' missed 43, 35 of
these Spamhaus caught - so for me Spamhaus is still better than
Barracuda. Also, I was sat in on a phone conference at Barracuda last
year where the motives were made clear; "Long term we intend to charge
for it" (OWTTE).
