No low TTL on the MX is needed, and if you want, you can use 'perdition'
to do away with the low TTL on the imap addr.

First, I would set hold_domains.

I would add a router to the current one to deliver all mail to the new one.

I would tell users imap would be unavailable for a sort period.

move mailboxes, test nw sesrver, unhold domains, update MX.
