Centos – Setting up DNS for e-mail serving

I have a CentOS6 Server and wanted to install Zimbra 7. I was getting an /etc/hosts error and found out that I need to run a local DNS Server due to split-dns issues.

I installed Bind and am trying to configure it.

In: /var/named/chroot/etc/named.conf

options {
    directory "/var/named";
    dump-file "/var/named/data/cache_dump.db";
    statistics-file "/var/named/data/named_stats.txt";
    forwarders {
        8.8.8.8 ;
        8.8.4.4 ;
    };
};

include "/etc/rndc.key";
// Specify that this server is the master for mail.domain.com
zone "mail.thedigiologygroup.org" {
    type master;
    file "db.mail.thedigiologygroup.org";
};

I dont know is using Google Public DNS is right here.

In: /var/named/chroot/var/named/db.mail.thedigiologygroup.org

@   IN  SOA     @ root (
                           10118      ; Serial
                           43200      ; Refresh
                           3600   ; Retry
                           3600000    ; Expire
                           2592000 )  ; Minimum

           IN      NS      @
           IN      A       75.149.56.27
           IN      MX      10 mail.thedigiologygroup.org.

Bind start correctly I switch the DNS servers on the NIC to 127.0.0.1 and try to install Zimbra again and I get the same error that started this process of:

`ERROR: Installation can not proceeed. Please fix your /etc/hosts file
to contain:

Where is the ip address of the host,
is the FULLY QUALIFIED host name, and
is the (optional) hostname-only portion`

my /etc/hosts is right with:

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.1.27 thedigiologyroup.org

So I am not sure what I am doing wrong.
