Thanks for continuing to work on the OTA solution. I'm getting ready to ditch my older WinCE 4.2 phone for a QTek 8500 (aka HTC StrTrk) phone that has Windows Mobile 5.0, and supports "Exchange Push Email".
I'm sure you guys have long ago dissected the Exchange (SP2) "push" functionality; I've read a little bit about it (it uses http-requests to sort of 'poll' the server, I think?).
Anyway - is the eventual Zimbra push-email solution going to mimick or be compatible with the Windows mobile clients that can talk to Exchange SP2, or... is there anything else you can tell us about it? I have ZCS NE 3.12 (upgrading them to 3.13 in an hour from now), and have not reviewed the source-code to see how the beta OTA sync works in Zimbra.
I couldn't find anything searching the wiki (searched things like "OTA", "push email", etc). If I missed it, just let me know :-)
