I once did a move where the servers were hosted on somebodyelses network and they were geographicaly seperated. I used IPTables to forward connections from the old server to the new one so the switchover was fully under my control, then the DNS changes followed later - this allowed for easy rollback.

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. -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
