and I am on a MISSION.
My current approach: use sbl-xbl.spamhaus.org and several of the
SORBS blocklists to start. Whitelist as necessary. For the next
week, monitor all the spam that gets through to my personal
addresses, and snarf the originating IPs.
Once I have a good list of IPs, I'm going to crawl through the
blacklists and see which ones will do a good job of catching much of
the remaining spam, then add those to the mix. And then whitelist
