The 'mail Queue' page isn't functional, I guess it's only a demo of features to come - don't forget that this is a developer build you've installed.
I assumes you mean the Server Statistics page for 'no data'? That seems to be an ongoing problem with some people, including me. Have you followed some of the diagnostics in the forum posts? Do a foroum search and see if any on the info helps you. I don't know enoiugh about Zimbra to help you diagnose this problem but I'm sure one of the Zimbra guys will be along later to help you.
