Why do you keep posting these messages in the Developers forum? You're not doing any Zimbra source code development and therefore it's in the wrong forum, I'll move it for you so please post questions like this in a more appropriate forum in future.
As I've said before, you need to search
bugzilla for any requests like this and file an RFE is you don't find anything. Requests in the forum do not get to the attention of the Zimbra Developers, bugzilla is the correct place.
