When you're dealing with 30 million incoming DSNs (this is not a
hypothetical figure), being able to reject them all at RCPT TO is
not much help.

I don't see why I should have to engineer my mail server to handle
5,000 times its expected workload just to accomodate all the bozos who
accept-and-bounce, uncontrolled backscatter, "sender verification",
C/R, and all the other cost-shifting methods out there.
