bind server doesn't do its job

[milimooli]

Hi There...
I just installed bind on RHEL 6 and point a domain to that server. but actually when i ping domain from network-tools web site, it returns error 1214:Unknown error
Here is my named.conf:

//
// named.conf
//
// Provided by Red Hat bind package to configure the ISC BIND named(8) DNS
// server as a caching only nameserver (as a localhost DNS resolver only).
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//

options {
    listen-on port 53 { any; };
    listen-on-v6 port 53 { ::1; };
    directory       "/var/named";
    dump-file       "/var/named/data/cache_dump.db";
    statistics-file "/var/named/data/named_stats.txt";
    memstatistics-file "/var/named/data/named_mem_stats.txt";
    allow-query     { any; };
    recursion yes;

    dnssec-enable yes;
    dnssec-validation yes;
    dnssec-lookaside auto;

    /* Path to ISC DLV key */
    bindkeys-file "/etc/named.iscdlv.key";

    managed-keys-directory "/var/named/dynamic";
};

logging {
    channel default_debug {
            file "data/named.run";
            severity dynamic;
    };
};

zone "." IN {
    type hint;
    file "named.ca";
};

include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";
zone "mydomain.com"{
    type master;
    file "/var/named/data/named.mydomain.com";
    allow-update { none; };
 };`

AND The content of "/var/named/data/named.mydomain.com":

$TTL 38400

mydomain.com. IN SOA ns1.mydomain.com. milad.yahoo.com. (
2012101201 ; serial number YYMMDDNN
28800 ; Refresh
7200 ; Retry
864000 ; Expire
38400 ; Min TTL
)

mydomain.com. IN A 1.2.3.4
www IN A 1.2.3.4
ns1.mydomain.com. IN A 1.2.3.4
ns2.mydomain.com. IN A 1.2.3.4
mydomain.com. IN NS ns1.mydomain.com.
mydomain.com. IN NS ns2.mydomain.com.

AND i'm sure the named service is running:

[root@server ~]# service named status

CPUs found: 8

server is up and running
named (pid 26299) is running...

Also here is the output of dig utility:

You cannot post links here until your post count reaches a minimum level - but that posting on Pastie is all in text. I'm sure you could cut-and-past that into a post here for reference, that way we can all see what is being talked about.
