An unplanned outage of IMAP service occured when
a mistake was made in the configuration of the
host based firewall for another virtual device hosted
by the same cluster hosting the back-end imap server.
A problem concerning console access to the cluster hindered correcting the firewall configuration error in a timely manner.
