I tried it for about two days. I had sales people complaining that
they couldn't get mail from their contacts; I had tech(!) firms' mail
bouncing back to them; etc.
While some spam comes from these unlisted people, most
comes from hijacked servers used for relay, which have perfectly
set up DNS entries.
