I've been giving it a try, and logging hits for black, white and yellow lists before my existing blacklists and content scans. Like a few other people, I'm a bit unclear about the value of the yellow list. I'm not sure I'd want to use it to bypass my existing blacklists (I'd rather risk false positives in spamhaus or whatever than let mail through because one of the listed servers once sent ham). And I'm not sure what other purpose it serves. The blacklist seems to be about as good as sbl-xbl.spamhaus.org, except it has false positives. Eg this one, which is one of the mx's of the European Bank for Reconstruction and Development: H=mx1.ebrd.com [193.128.202.111] Warning: black - dnsbl - mx1.ebrd.com [193.128.202.111] The whitelist seems to be OK, and if I could rely on it 100% it could save some content scanning effort. But in my very small test, I had only 3 hits: one google server, one blackberry server, and sesame.csx.cam.ac.uk. On the other hand, some major bank servers (citigroup and state street for example) are listed as yellow. So the white list doesn't suit my (admittedly niche) purposes.
