How to stop the rewrite of bind configuration?

I have found the /etc/bin/named.conf.options has been rewritten. This has caused problems with the email by several days, until somebody complained about email problems.

My file is this:

Code:

include "/etc/bind/rndc.key";

controls {
    inet 127.0.0.1 allow { localhost; } keys { "rndc-key"; };
};

acl "trusted" {
1.1.1.1;
2.2.2.2;
127.0.0.1;
};

options {
    directory "/var/cache/bind";

    //query-source address * port 53;
    //query-source    port 53;

    empty-zones-enable no;

    //dnssec-validation auto;
    //auth-nxdomain no;    # conform to RFC1035

    listen-on { trusted; };
    listen-on port 53 { trusted; };

    version "unknown";

    allow-notify { trusted; };
    allow-transfer { trusted; };
    allow-query { any; };
    allow-recursion { trusted; };
    allow-query-cache { trusted; };


};

logging {

    channel default_file {
        file "/var/log/named.log" versions 3 size 5m;
        //severity dynamic;
        print-time yes;
    };


};

and I have found this new file:

Code:

options {
  directory "/var/cache/bind";

  // If there is a firewall between you and nameservers you want
  // to talk to, you may need to fix the firewall to allow multiple
  // ports to talk.  See http://www.kb.cert.org/vuls/id/800113

  // If your ISP provided one or more IP addresses for stable
  // nameservers, you probably want to use them as forwarders.
  // Uncomment the following block, and insert the addresses replacing
  // the all-0's placeholder.

  // forwarders {
  //  0.0.0.0;
  // };

  //========================================================================
  // If BIND logs error messages about the root key being expired,
  // you will need to update your keys.  See https://www.isc.org/bind-keys
  //========================================================================
  dnssec-enable yes;
  dnssec-validation yes;
  dnssec-lookaside auto;

  auth-nxdomain no;  # conform to RFC1035
  listen-on-v6 { any; };
};

Is there some option to import my file into ISPC to be adopted and preserved ?.
On the contrary, Where can I include these parameters of named.conf.options inside ISPC?. I cannot find a place

 

thanks!
