I am not new to Zimbra having done many many installations. I am running on Ubuntu server 8.04 and upon installation, the domain shows as mail.company.com. So the e-mail addresses are firstname.lastname@example.org instead of email@example.com. The host name IS mail.company.com and that's the way I want it but I don't want it that way for routing mail. Why does the new install do this and how can I fix it. If I re-install and change the hostname, it's just gonna give it the new hostname as part of the domain name is my fear. Can I just set up a new domain in the admin panel to fix it? If so, what do I have to do to accept and send mail for company.com?
