    It is in a DMZ. That "private" IP name server is from VMWare Server 2 as I have Zimbra running from inside a VM (CentOS 5) on a host Win Xp Pro machine. It is all handled via the "Manage Virtual Networks" app from VMware and set by default.

    Inside of this Manage Virtual Networks is where you NAT/Port FW and I have.

    I even tried putting in the VMWare (that private IP) DNS piece a line stating: #externalIP# -> #InternalIPoftheserver# to stop it from trying to go out to the Internet for name resolution which is stopping LDAP from starting up properly as seen above.

    This really is frustrating and I know the setup is not optimal but it is for some preliminary testing. It seems like the whole issue is Zimbra trying to call itself internally from the external IP always.

    Well, I had ZCS running under a Xen Dom-U before and had no issues with CentOS. Just install BIND on the ZCS server and point /etc/resolv.conf to it. Setup the A and MX records and you can add a forwarder for everything else.

    I am doing an uninstall now, and will reinstall to see if other changes were causing issues. If not, then i will try the local DNS/BIND route.

    Thanks! I'll keep ya posted

    OK, so i remember getting this the first time I installed too... how should I answer?

    Code:
    Installing packages

    DNS ERROR - none of the MX records for server.no-ip.org
    resolve to this host
    Change domain name? [Yes]
    So, do I:

    A) Change my hostname to something like localhost.localdomain since the box is not truly directly on the net with the external IP. Reboot and then re-install Zimbra.

    B) Keep the hostname set to the FQDN/Dynamic DNS and answer NO

    C) Keep the hostname as-is and answer YES changing the domain to localhost.localdomain

    D) Some option I have not thought of

    Thanks!

    Install a split DNS as I have already said ... Give the server a A and MX record of 192.168.164.128. As you are performing a effective NAT in VM in will accept the SMTP traffic then and deliver correctly.

    I'd love to, but the problem i am hitting is that the new version of Bind does not have a named.conf as all of the guides reference such as the Split DNS tutorial. Do you or anyone know of an updated guide for CentOS 5? I really would like to get this working.

    SOLVED!

    Oof... that was painful. And thanks for all the help!

    Setup split DNS and set /etc/hosts to the internal IP address. can now send and receive properly.
