This might be fine on low loaded systems, but to do a lookup for every 
email on major networks would fail, as sql would not keep up unless you
clustered and nobody is going to do that just for whitelisting.

I've seen it with vpopmail for instance the cdb file can handle over 6000 
concurrent connections with no ill affect, sql spits farts and dies at 
1/5th of that value unless you cluster, so it's a pointless expense.
