I just got Zimbra Desktop 2.0.1 (build 10659) installed on Ubuntu 10.10. It works beautifully for my Zimbra account and my Yahoo account. I am not able to get my IMAP account (from lavabit.com) working on it though. I can add it just fine. The settings match what I have in Thunderbird (which I would like to replace with ZD). When I try to open the folders for the IMAP account, I am presented with a "Failure communicating with remote server" error. Clicking Show Details reveals that it does actually connect, but fails when synchronizing the Drafts folder. Does anybody have an idea as to what could be the problem here? I'd really like to use this exclusively.
