We are currently in the processes of designing a live development and test environment. they will be in seperate forests with a two way trust the production domain. I am wondering how to setup so that both test and development will be able to send emails within the organization (Production, development, and test domains) as well as to email clients located on the internet. Both the test and development domains will be using the internet connection that the production domain is currently using.
I am not sure how to do this or how it will work given that the test and development domains have different domain names than the production domain.
Is it possible to get something like this working? Please give an example of how it can be done. i don't need step by step config details, just an overview.
Thanks in advance.
