I have let's say domain x.com and domain y.com.
My users needs to get mail from both x and y, but due to legal reasons, the mail must not be in same mailbox. I guess if I exchange opens the user and under SMTP enter email@example.com and firstname.lastname@example.org it will end in the same mailbox, which is not legal in my case.
Can a user have several "Inboxes" (physical splitted mail files) in Exchange?
I hope you know what I mean - it's difficult to explain.
