Add a new MTA to a non MultiServer install!
We had a Single Server all in one box install of Zimbra. But, my email traffic is increasing, and my machine isn't handling it anymore... I'm thinking on put a dedicated MTA server to load balance the work.
What I need to do? Can I follow the multiserver install guide (presuming my current install will be the LDAP/Store) and follow installing the MTA server?
Will this work? Or I will need to re-install everything? And if it is needed how can I migrate my current users/mailbox to the new configuration?
Thanks in advance!
