I have a zimbra mail.example.com box I'm testing to see if I like it. 2 questions:
1. On a traditional postfix box I can map email@example.com and firstname.lastname@example.org, is it possible to map multiple virtual domains/users on the same zimbra box?
2. On a default install, it seems zimbra wants to take the mail form email@example.com, really what I want is just the firstname.lastname@example.org. I have a valid mx record for example.com, can I just change /etc/hostname to example.com instead of mail.example.com, or am I oversimplifying, what else do I need to do?
