Then again such a hypothetical database would be mostly useless in

There's an even bigger problem - you have to make the difficult choice between:
1) Flag the DMZ mail server of every site that uses RFC1918 space, since the
hop" is in their 1918 space. This won't win you friends....
2) Allow a "pass" for 1918 space, and just accept that spammers will use a dummy
RFC1918 network (of possibly 1 node looped back to itself) to "look like" (1).
