I have a customer that has an Exchange server that is running multiple email domains. Everything is working fine except they have an old domain that the server is sending out from. They want to have abotu half of thier user send out on one domain, and the other users send out from the other domain. They all need to be able to recieve on all domains. I have setup each user default address, but this does not seem to be doing what I want it to do. How do I set things up so that when they send mail it sends it out using the desired email address?
