While I don't think that it is as bad as spammers, it does seem like throwing
gasoline on the fire. Say I get 1000 bad addresses. I have just doubled that
by verifying. If I got one million, now there is 2 million. And you aren't
punishing the spammer. You are punishing the poor server that was spoofed.

There needs to be a smart verifier that does a dns lookup first to see if the
mail even came from a valid ip address for that domain BEFORE it even
considers doing a verify. That would drop a lot of the crap without punishing
poor Mr. Innocent's  server.
