Strictly speaking this is a bad thing to do, you should only use it to
weight a spam detection algorithm, but that said, I use them raw so I
shouldn't really be talking, but blocking stuff at the smtp stage is
preferable so direct implementation is excusable, just watch blacklisting
local isp's, might want to whitelist their server ip ranges.

I use the following list, with a couple of allow overides to keep me from
blacklisting ISP's, I know admins with up to 36 lists but the lookup
overhead -v- current crud getting through doesn't make it worth it.

Generally takes more than one to get things under control, but if you want
to cut down on lookup times and work from cached entries, run a localhost
copy of bind, and hook it to the above authorative hosts for answers, and
then you'll have one localhost lookup which will cache results from the
above you'll get faster results and be kinder to the bandwidth of the
