I was just playing with this today - I'm not sure I'd put much faith in surbl.org. The first two messages I saw it tag in my own inbox, were very legitimate.  In fact, one of them was from Wells Fargo (*really* from Wells Fargo, sent from Wells Fargo's own mail servers). I find this ironic, since one of their new features, is whitelisting publicly traded companies. :)

Hi,
 
Today I finally took the time (I didn't have) and ran both Sniffer and SURBL Tests (using http://www.invariantsystems.com/invURIBL/).
 
Result:
 
  1,860  tagged by invURIBL only -> gain over Sniffer = 21%
  8,926  tagged by BOTH invURIBL AND Sniffer
     962  tagged by Sniffer only -> gain over invURIBL = 11%
 
In other words:
 
If I ran ONLY Sniffer, I would have missed 21% of additional messages that were detected by checking against SURBL.
If I tested SURBL only, I would have missed 11% of messages (that only Sniffer found)
I have configured Declude, so that the two tests are complimentary (no extra weight BOTH tests vs. ONE test fails.)
 
My conclusion:
 
Both Sniffer and invURIBL are worth their money...
