Hi All,
I want tried to create a mixed environment between Zimbra and Exchange.
My Existing Mail Sytem using exchange 2003. I want to create zimbra as my front-end for my exchange.

I already install zimbra on ubuntu 8.04 and My User Authentication via Active Directory. Zimbra can forwarding to exchange server using "zmprov ma rengga.patria@metrocom.co.id zimbraMailTransport smtp:mta1.metrocom.co.id" command.
But the issue is why zimbra can't keep email on zimbra mailbox.
I Want all email recieve by zimbra mailbox and after that forwarding to exhcange server.
Any idea ?
