I spoke with Scott Hawkyard in sales yesterday about this, and wanted to post it here for the cogitation of mobile developer types.
If the ZME client works out well -- and I can't eval it, because neither the Pearl nor Generic versions will run on my 7100i, damnit -- then it will probably be my preferred way to deploy Zimbra mail for my coterie of executives with Blackberries and Blackjacks, etc...
There are two reasons for this:
1) Blackberries are *notoriously* poor at dealing with enormous local mailstores -- my 7100 has pretty close to every message I've ever received on it still on it, over 2 years, and it takes over 12 minutes to cold-boot, and garbage collects *way* too often... and executives are notoriously poor at cleaning up their mail. So, if I can run ZME on the handheld -- which presumably acts like an IMAP client to the server-based mailstore -- then that would be good, yeah.
2) Replies from said executive would then *also* go out via the server... hiding the fact that they were sent from the mobile, and also it's direct address, which
3) (ok, so I lied) means that all the followup mail will *also* go through the office mailserver, and thence be searchable, etc.
The *problem* I see here, is this:
In order for this to work practically, I cannot assume that the client will be a) running in order to b) notify the user when new mail comes in -- I don't think there's any way to force a BB app to start on boot, and auto-restart, as would be necessary to simulate push with the client.
So, alternatively, you need some way to send a magic SMS to the client handset that will set a notifier, and optionally launch the client. And not show up in the phone's local message list.
Any Blackberry Experts out there?
I'm sure there's a magic bullet way to do the push notification...
