We whitelisted cheetahmail.com in SURBLs, presumably because we
saw false positives on it, as you suggest.
I personally don't use ahbl for blocking at any level.
sbl-xbl.spamhaus.org, list.dsbl.org and combined.njabl.org
are the ones I usually recommend at the MTA level, but they may
be too strict or not strict enough for some situations.
Don't harm innocent bystanders.
