Yes - don't worry about it, it doesn't matter. You don't need to be
able to resolve sbl.spamhaus.org because that's not how blacklist DNS
lookups work. If you want to check if the IP address 1.2.3.4 against
sbl.spamhaus.org you need to check

4.3.2.1.sbl.spamhaus.org

If it doesn't resolve then 1.2.3.4 is not in that list - if it resolves
(to 127.0.0.x) then it is in the list.

Don't worry that you can't resolve sbl.spamhaus.org by itself - it's
irrelevant.
