I just got zimbra up and running(latest and greatest version). It's pretty sweet. I have only two problems.
When I login via the admin console and select a user then click on "view mail"
It brings me to a page http://mydomain.com/zimbra/auth
But that page doesn't exist on my server so I never get to see the users mail.
It seems that the preview pane is not working. No matter how I set the pane options I always have to open the email to read it.
