You are certainly correct that most zones are pretty flat, but this
sounds like a DOS attack waiting to happen, send out junk with long
bogus addresses
I'm just raising this as a discussion point; what if we said that the
SSP record must (at least) exist at the registry cut-point?
It's not particularly pretty, but you (only) need about a 1,000 entry
database to define all the registry cut-points today. I know the size
because we've built this sort of database for other reasons. I think
SpamAssassin has something similar as well.
FWIW, here's what we use for cut points:
http://svn.apache.org/viewvc/spamassassin/trunk/lib/Mail/SpamAssassin/Util/RegistrarBoundaries.pm?view=co
surbl.org and uribl.com use the same cut points since they're mostly
used by SA.
