We have Exchange 2003 and the mail domain is @domain.com. We now have a new domain @second.com that is coming in through our exchange server. I set it up correctly to receive these on an individual basis (putting it in as another email address on a user), but I'd rather set up the new email address from the different domain as a distribution group using our users on the server, but using the different domain (firstname.lastname@example.org). I can set up a distribution group with the server's domain (email@example.com) but I can't get the distribution group to work for @second.com email addresses. I'm sure I'm not doing some settings right. Any help? Thanks!
