I'm guessing SpamAssassin will distinguish between
- fail
- unknown (record exists)
- unknown (record does not exist)
and score the first very negatively and the second slightly negatively.

All in good time. Nobody will thank us if we break things. We need to
go slowly and solve the forwarding problems to keep the FPs down. Then
we can ask everybody to switch to -all.
Right now we need:
1) more publishers
2) a solid sender rewriting scheme
3) SPF patches to go into MTA distributions
4) SRS patches to go into MTA distributions
5) forwarding providers to do rewriting too
