We get about 50-100 spam samples every day (we don't need more, thanks ..)
and use them to update our lists. Please note that this list only handles
1/3 of our spam filters. The blackholes.wirehub.net DNSBL is just as
important. Both databases have a degree of 'self-learning'. Hits on the
address/domain blocks find their way into the IP-based blockers (when a
patterns emerges), and new spamming domains from already listed IPs get
added to the spamlist. Any of the blockers will get you a nice result;
combining them is the way to go.
