Setup Exchange 2007 Servers in multiple locations
Posted on 2008-10-13
Hi Exchange Experts-
I am going to be setting up Exchange 2007 servers for my company. I have read up on the preliminary groundwork for the setup and here is what I found you need:
-2 Domain Controllers for each organizational site
-1 Mailbox/ 1 HUB / 1 Client Access Server at each location
-Edge server is optional
I have 5 total locations. What is the best way to implement mail servers to go across a SINGLE domain and how will the mail servers know which location to go to?
In example, if I have email in Italy and have the setup above, how will the mail server know to route the email
FROM ITALY to ITALY (and not go out ITALY->Mail Gateway in US->back to ITALY)
or FROM ITALY to US
or FROM ITALY to OTHER GLOBAL LOCATIONS.
I was thinking MX records but that is usually for split domain or load balancing.
How would the mail server know that a user in Italy is a user in Italy and deliver it there? (does it check an OU on active directory and if the user is there it accepts mail?)
I'm looking for best practices in this specific setup (single domain, multiple remote sites, single or multiple gateways).
Thank you in advance!
