Re: [diningphilosophers] Re: Ms exchange protocol in Java? Architecture

Hi Folks,   Sorry for the late reply,   I made some research on this kind of application one month ago.. Please see attached image file  of my original sketch.  My original requirement was to synchronize google apps with exchange server..    However, I think if build a Messaging Synchronizing Gateway (MSG) that sits between google apps and exchange server,  the MSG will work for other mails servers as well (appart from that of google apps/exchange server).   In my original MSG, I just wanted to implement a simple smtp (for mail push) and pop3 (for mail pull) in the gateway..  This was going to give me the power to mirror all my local exchange mail accounts with a corresponding google app mail account use for sparm blocking, backup ete...   What is next ?   I think we can meet offline to match our requirements, download some open source java (or C#) smtp and pop3 mail clients and modify it to work as a background service doing the synchronization. Ofcourse, we also need to design and code the interface to configure the MSG parameters.   What do u guys think? Who are those interested ?  2 or 3 developers working weekends on this project can get it done in 1 month.   Best Regards, Leo.                 --- On Sun, 16/8/09, Huaping Gu <humph...@gmail.com> wrote: From: Huaping Gu <humph...@gmail.com> Subject: [diningphilosophers] Re: Is there any implementations of ms exchange protocol in Java?

Hi Leo,

It looks like the same philosophy of Google Calendar Sync tool, which
works as an outlook plug-in and synchronize data between exchange
server and google calendar.

The advantage is we don't need to dig inside the protocol of exchange
server as this tool only works as a normal client (or even more simple
as a message receiver).
The negative point is we have to keep it running on a PC that will not
be turned off. (It's ok for me as I never turn off my desktop pc in
the office).

Another drawback is, if this MSG receives mails forwarded by the
exchange server (might be our local account), it increase the network
traffic twice. (Each mail I receive will be forwarded to this tool
first and then be forwarded again to the destination device which
might be cellphone or google mail account). This needs to be taken
into the consideration.

Thanks and regards,
Henry
