I'm working on integrating Zimbra with our intranet home page. We'd like to display users' inboxes and calendars on the portal, and allow them to click on a email in the portal and go straight into Zimbra to view that message.

I have successfully built the portal up to the point where users can click a link to go stright into Zimbra without logging in (using pre-auth), but I'm not sure how to have Zimbra open up a specific message automatically. Is this possible? I'd also love to be able to link directly to a specific calendar item or day, as well.
