As long as the senders' MTAs are RFC compliant nothing bad can happen unless
all real MXes go down, and in that case there is no difference between having
a fake MX and having no fake MX, whether the fake MX gives a temporary error
or doesn't respond at all. And even then you're not *losing* mail. Having mail
bounce back to the sender is not losing mail (although it can mean losing
business). Having mail disappear without any notification is losing mail.

The RFCs don't require 100% uptime. The RFCs don't say that you can't lie
about having a temporary error condition. It does say that sending hosts must
try all MXes in order.

Except that the garbage disappears and noone has to clean it up. It's more
like posting a sign saying "<- entrance through the next door" that makes
spammers go away.
