Hello, I am in the process of decommissioning my own personal email server which is running on an antiquated version of CentOS and an old version of Postfix (2.3.3) to a Debian 7 server running Postfix 2.9.6.
I've got a tool for copying the IMAP mailboxes from the old server to the new server. What I'd like to do next is figure out a way to have Postfix instead of delivering to the local maildir on the old host deliver it to the maildir on the new host either by injecting the mail into the queue on the new host or some other means. What I'm trying to prevent is either generating false bounces during the change over of the MX records to the new host. Thinking ahead I'd also like to use that capability to set up another host to act as a secondary MX for my personal domain. Thoughts anybody?
