A little background...we're trying to act as a remote mail server from our corporate server which is running postfix. The corporate office will route/copy mail to our server, but I want local mail (mail between local zimbra accounts) to route without going to the corp mail server. Currently, I have a separate mail domain than the corp office.

We thought that we could do this via virtual user mapping. In postfix, we'd do this:

postmap user@OtherDomain LocalUser

We've tried to use the zmprov with the ma and aaa options without success. Is this possible in zimbra and if so, how?
