I have a private mail server that is my primary mail, this server is a linux server I access through IMAP.

As a backupsolution, I've added the same email address to gmail, and configured the gmail mx servers as secondary mx servers.

I would like to be able to access both of these accounts from Zimbra, but the setup complains that email is allready in use.

Is this possible to solve with zimbra? (it works just fine in thunderbird, live mail and outlook)
