It looks like the mail server at arc.tusc.k12.al.us is FUBAR. The "421"
code means that the server isn't accepting mail right now, but will very
shortly (it's used during reboots, for example). IMail takes this as
meaning what it says, and it waits and tries again later.
It looks like the problem is that their mail server is stuck in that "Gee,
I'm almost ready to accept mail" state. Some mail servers may try the
backup MX records, which would explain why they get get some mail. It's a
problem on their end that they need to fix.
