IMAP server stuff
I think we've got a nice solution to the IMAP server upgrade that will really minimize downtime, which is great news. Since the current IMAP server stores its disks on an external fibre-channel RAID box, we'll just connect this box to the new server (once we buy an HBA for it) and move the mailboxes to the new filesystem using the Cyrus IMAP software itself, which can move live mailboxes similar to the way AFS can move live volumes. This means that we really only need an outage lasting long enough to move the RAID array, which shouldn't take more than about 15 minutes. Very cool.
