Does Zimbra currently have any intention to implement the Exchange Active Sync Mailbox policies or remote device wipe?
(See Understanding Exchange ActiveSync Mailbox Policies
and Understanding Remote Device Wipe
for details about what this all does.)
These features are in EAS, clearly, so that the Windows Mobile platform can compete, in terms of security and enterprise manageability, with Blackberries.
But Apple also intends to put these facilities into its EAS implementation for the iPhone (Apple - iPhone - Enterprise).
For those of us who would like to be able to do Zimbra/iPhone as securely as one could do Exchange/Blackberry, adding this would be a great thing.
