I installed zimbra on ubuntu 10.4 from a documentation. I configuered the hostname, dns as mail.example.com. I installed zimbra and its working perfect.
The only problem is i can send/receive email from/to email@example.com only not from/to firstname.lastname@example.org. Can anyone help me how to resolve that issues.
I want to take out the mail part and want to keep only example.com as my domain.
