we are thinking about migrating from our current LDAP to Active Directory and Exchange. At the moment we have some offices in other parts of the world that send their mail to our SMTP server using their own e-mail addresses with country extension.
For example, the people in korea use something like firstname.lastname@example.org and it goes to our SMTP server which is server.domain.com and then out to the proper location.
Can the same functionality be setup with AD and Exchange or is there an easier way of doing the same thing so that they have their countries extension on the domain and not the .com one? Or is this merely a DNS routing issue where you would have to setup MX records pointing something from that domain to our SMTP server?
