Lack of inclusion in SBL can and probably should be a flag to check for FPs, but there are spam domains, especially new ones, that sometimes don't match SBL, for example due to using a new name server or hosting IP space.
OK, I'll rephrase my question:
If the ones that do have name servers listed in SBL where sorted out in an automatic process, would the number of new daily domains left be small enough to check manually?
We do checks like that, and its like 15-20% thats listed inside SBL with nameservers. So, or us, no. Helps a little, but not enough.
I agree, there are some SBL hits, but they are probably a minority. More like an occasional extra bonus flag of spamminess. ;-)
