My present setup is a single imap proxy with 6 mailbox servers using perdition. At this time we are evaluating zimbra network edition. We are thinking to switch our imap proxy with zimbra-proxy/nginX. So the question is do i need to make changes in my mailbox servers ?
Also is there any option to use perdition instead of nginx ? I am thinking that if ZCS allows perdition, then I don't have to make any changes at the mailbox servers. Am I right?
