GigaOM : Zimbra, EMail Done Right: "I would go out on a limb and say that it combines the best of both Microsoft Outlook and Google’s GMail! Plus, Zimbra has this “search and save search feature” that is very much like Apple Mail’s smart mailboxes. (This save search feature also helps the company over come the inherent problem of filing everything away in folders. The conversation view of Zimbra is what really really rocks: it puts everything in context, I can tag it accordingly, for my own use later. "
Great to see innovation in the messaging market again.
