Exchange 2010 and exchange 2003 co-exist at two different sites with different accepted domains
Posted on 2010-11-30
So I'm looking for the best way to setup my exchange org. I have an exchange 2003 server in London (LON) and one in Philadelphia (PHL), same exchange org, primary server MX point to LON. I have just installed the first Exch2010 in PHL (after raising all functional levels for AD and exch). 2010 will replace 2003 in PHL.
I am now presented with configuring my send connectors. I will be accepting mail for two internet domains, one in LON and one in PHL.
LON = abc.co.uk
PHL = abc.com
I would like email from PHL (abc.com) to be sent from Exch2010 in PHL
I would like email from LON (abc.co.uk) to be sent from Exch 2003 in LON
I would like email from PHL (abc.com) to LON (abc.co.uk) to be sent over our VPN - not over the internet.
What is the best method for configuring my send/recieve connectors:
PHL Exch2010 - Default send with * Address space using DNS and PHL Exch Source
Do I need a VPN send connector:
PHL Exch2010 - VPN send - abc.co.uk Address space using smart host address of LON server and PHL as Source???
For receive, I will be using MX logic, so I will configure new MX for PHL (abc.com) and a receive connector to only receive from MXlogic and lock down firewall ports accordingly.
MX and receive for LON will not be changed.
Do I need a receive connector on exch 2010 to accept from abc.co.uk? Will I need to make any changes on LON Exch2003 to accept from PHL abc.com?
I will also need communication between PHL Exch2003 and and PHL Exch2010 during the time it takes to move mailboxes from Exch2003 to Exch2010.
Any thoughts on this are greatly appreciated.
