Would this be better run as a script launched from cron?  Maybe every 5-10
minutes a script could see if the IMAP port is responding.

Currently I'm pondering doing either this or running Mon to monitor the IMAP/s
ports, the SMTP ports, the MySQL database, and anything else I can think of
between now and then.  Mon lets you write your own response scripts, so you
could decide whether it shuts off your IMP pages or merely puts up a "The
server is down" message in the motd.
