I removed sbl-xbl.spamhaus.org a few weeks ago when their legal troubles started; it was causing me SMTP timeout problems back then. I tried putting it back once about a week ago, and as soon as I did my SMTP connections started taking forever. I also removed the others because they either didn't respond to pings (not a big deal, many servers don't) or they didn't resolve to an IP address (I don't think that is good). I would try sticking just the servers that you know are good in there first, then add the others one at a time.
