Hi Group,

I'm new to Zimbra and have a few questions. We are a service provider and have been using Qmail for a long time now. We are looking to move beyond it because of the lack of a web front end other than squirrel mail.

1.) Is the Zimbra Open Source product suited to the service provider customer? We have many customers, each with their own domain.

2.) Do users login with email address or username? I ask because it is possible there are users with potentially the same username under different domains (aka sales@domain1.com and sales@domain2.com) etc..

3.) Besides general LDAP support, is there any other included support/features in the open source version for droid/iphone ?

4.) MS Outlook is supported on the desktop right?

5.) Any shared calendaring functions in the Open source product.
