no i am not kidding you
what i linked is how in professional environments typically things are done - virtually nobody would talk from one IMAP server to another one to deliver mails to the client
with clustedred and replicated filesystems you have all servers accesing the same mail storage and your DNS-record has all of the servers listed

so before you assume someone is kidding you google how load balancing is done in large environments, read the links others provide and if you are not on a that large environment one server would be enough

Are you kidding me? Is not how or where to store the mailboxes... is how to connect an imap server to another IMAP server that have mailboxes!
