Actually I would prefer that we consider hacking smtp to have it perform
a verify on the incoming mail's origin and reject any attempted
connections where that host is not reachable. I tire fast of the mail from

make.lots.of.money@just.send.me.ten.dollars

Basically if I would not be able to reply to a mail sendmail would not
deliver it. Yes, some mail is rejected if a host goes down at precisely
the wrong instant but that would be uncommon.
