Hi,
i have follow this guide to install Zimbra CS 6 on a CentOS Zimbra Collaboration Suite Open Source Edition On CentOS | HowtoForge - Linux Howtos and Tutorials
Zimbra work perfectly but the domain name in Zimbra is "mail.mydomain.com", not "mydomain.com"....my mailbox is "name@mail.mydomain.com" instead should be "name@mydomain.com"...what to do?

Thanks
