I have to perform an Inter-organisational migration from Exchange 5.5 to Exchange 2003. My initial testing allowed me to get message flow working but with each org had a different SMTP namespaces. I have realised the in place migration will actually have the same SMTP namespace in each Org. Microsoft documentation talks loosely about creating an SMTP connector to allow message flow between the organisations but I cannot see how I am meant to distinguish routing between Orgs. Has anyone tried this or can advise want I need to configure....the model is One NT domain connected to a New AD domain with then the 5.5 Org part of NT Dom and the new 2003 Org part of AD? Thanks
