the web client (Ajax) interface look and work like Outlook. it's a possible new business to host MS Exchange like email/communication for business. there already people asking to use Zimbra for hotmail like service.
i don't have a linux server so i was wondering how many host out there have try out Zimbra and if you guy think it's a possible new business to offer service based on this new opensource project.
Zimbra's public license package is available for free of charge, however their standard edition is available for $30 per mailbox per year, it looks nice, I am awaiting for some more features to be added, such as multinode clustering capabilities etc.
