Want to create DC DR Mailbox server

[jayesh shinde <jayesh.shinde@xxxxxxxxxxxxx>]

Hello all ,

I require suggestion for building up the DC  DR server. I want to build the Mailbox server with 5000 users , 1 TB size of total mailbox data.

1)  DC and DR server will be in two different IDC , with internet connectivity or with dedicated pipe.

2)  How to sync the every email ( add / delete / seen / unseen ... etc )  on the fly from DC to DR ?
     Please share if any have good URLs / Blog / wiki / howto steps information  for implementing the above.

3)  If point 2  have solution , then in case of drill if I point the LIVE IP from DC to DR and if all emails come on DR server for 1-2 days , then how to sync back that emails to DC again.

4) For syncing data back from DR to DC , Is there any method other that IMAPSYNC ?

5) Is it possible again on the fly syncing of emails from DR to DC ?

6) How other sysadmins are managing the Drill situation and DC to DR syncing ?

Regards
Jayesh Shinde
