Hi all, we are in the process to migrate from a Domino-based architecture to a Zimbra-based one. We would like to set up a Zimbra MTA and a Zimbra POP/IMAP server on different machines and preserve the Domino server (split domain). Now the problem is, if I want the MTA to be the authoritative server, should I configure all the accounts there? Is there a way to get them from the Domino/Zimbra proxies via LDAP? Or maybe should I change my architecture and let the Zimbra proxy be the authoritative? If so, again should I configure all accounts on it?

Thank you for your time.
