    Unhappy [SOLVED] DNS ERROR resolving MX for mydomain.com

    Hi
    I am Kunal and very much new to zimbra. would like to take zimbra on a test run but can't get through the installation.

    We have 1 vmware vsphere host with Windows 2008 server as AD DC, DNS server

    Now I have installed zimbra on ubuntu 10 (64 bit) with zcs-7.1.1_GA_3196.UBUNTU10_64.20110527011124.

    I am getting stuck at "DNS ERROR resolving MX for mydomain.com"

    windows 2008 dns can resolve mail.mydomain.com to ubuntu/zimbra server.

    bind 9 can also resolve mydomain.com and mail.mydomain.com as I have set the nameserver of my windows server under "/etc/resolv.conf"


    so where should I set the MX server details ? I have already have mx server details on my windows dns .

    Please help as I don't know whatelse to do . I have looked at the old posts too.

    This 'problem' has been covered all over the forums and in a wiki article. Go to the Split DNS article and read the instructions there, you can run all the commands in the 'Verify...' section of that article to confirm your set-up is correct - that article tells you all you need to know to correct your DNS.
    Regards

    Ok Phoenix

    I followed steps mentioned in Split DNS

    I had bind9 installed with Ubuntu installation so lot of things are not matching
    e.g my named.conf.options is under /etc/bind/named.conf.options

    also if I add "include "/etc/rndc.key";
    my bind 9 fails to load and "zone "server.example.com"

    says invalid option "zone"

    when I type in "named -g -p 53"


    I also get the following errors. I have used
    Split DNS - Zimbra :: Wiki

    and

    https://help.ubuntu.com/community/BIND9ServerHowto

    and here is some error you may point me with a right solutions

    09-Jun-2011 10:53:27.802 zone mail.mydomain.com/IN: NS 'mail.mydomain.com' has no address records (A or AAAA)
    09-Jun-2011 10:53:27.802 zone mail.mydomain.com/IN: not loaded due to errors.

    The section highlighted in red indicates you have no A record and the highlighted section in blue indicates you have an incorrect formatted DNS record (it's probably missing a '.' (a period). I don't use Ubuntu so I can't help you with the file locations, you could always use Webmin to modify the DNS records, it's a useful web UI for server management. There are also a couple of articles on Ubuntu & DNS in the wiki if you'd care to search for them.

    Default Solved

    OK
    I have got it resolved. What I did was trying to get bind9 to work using bind9 installation and then zimbra. that was a mess. Anyway so I recreated my virtual machine and re-installed Ubuntu. remember do a ubuntu only and do not install any packages line bind9 , lamp etc.....

    then simply follow bind9 steps on
