I need to work with few domains, but am reluctant to host them on same machine as ideally some of the companies we invest in should not be linked together. Since the headers contain the FQDN we currently use two e2k3 servers and have them in separate forests. I red about rewritting in e2007, but not sure I understand how it works. Can we host our domains with exchange 2007 and maintain this separation of headers as far as server FQDN goes? I understand headers can be rewritten, but the address rewriting agent seem to be changing the e-mail addresses as far as understand... will the server FQDN always appear the same? Thanks George
