Forgive the question, but whats the difference between an IP that is down
because of lets say Scheduled Network-Maintenance _and_ an offline host ?
Perhaps I am wrong but to all intents they appear the same, yes ?

Although it's very easy to say that a 'off-line' mailhost should

Indeed. It's rude to put an IP address into a global DNS record if
the
address isn't globally reachable. You're wasting valuable client
time
that could have been used for successful deliveries to other hosts.
Most MTAs, under most circumstances, will try at least two MX
records,
but if you're relying on this then you should fix your
configuration.
