Hi there, |
| 34 |
|
| 35 |
This is something I'd love for Gentoo or any OSS alternative to do - I've got a Windows Mobile 5 device, and currently have an old machine just |
| 36 |
running Windows 2000 and Exchange at home for my push e-mail which frequently breaks (like today when Windows rebooted automatically for a hotfix and |
| 37 |
the machine didn't come up again) |
| 38 |
|
| 39 |
As far as I know, DirectPush uses a GPRS connection only (it won't use the built-in WiFi on the phone if available) and basically sends a small "ping" |
| 40 |
request every minute to the server over IP, which the server replies to telling the device that there are no new messages or new messages in which |
| 41 |
case it opens a connection to the server to sync. |
| 42 |
|
| 43 |
I had to load a service pack onto my Exchange Server, as well as onto my Windows Mobile device to get DirectPush as an option, I'd just love for this |
| 44 |
to be an option for any IMAP enabled server (as far as I can make out it uses the Exchange Outlook Web Access functionality for DirectPush to work) |
| 45 |
|
| 46 |
Maybe this will be something Microsoft will open up as part of the EU investigation which means they must publish interoperability specs for their |
| 47 |
API's? |
