If I'm understanding what you are asking correctly the answer is, yes
mail will still forward on, but only when mail.msu.edu is back up. In
the situation where everything is down, the original sender's will queue
up the message on their end as "Host unreachable" and their SMTP
software will attempt to retry every so often (it all depends on what
their config is).
If mail is up and running but just being hammered down and "unreachable"
to our users, chances are pretty great that we will be the ones queuing
up the emails waiting to forward them on when the queue-runners get to it.
To sum up, email should always (eventually, heh) be coming through. Let
me know if I misunderstood.
