Ошибка лишнего ввода текста в файле зоны привязки centos 7

я хочу настроить dns для домена bazim.ir с помощью bind; это мой файл /etc/ named.conf :

options {
    listen-on port 53 { any; };
    listen-on-v6 port 53 { any; };
    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; };

    /*
     - If you are building an AUTHORITATIVE DNS server, do NOT enable recursion.
     - If you are building a RECURSIVE (caching) DNS server, you need to enable
       recursion.
     - If your recursive DNS server has a public IP address, you MUST enable access
       control to limit queries to your legitimate users. Failing to do so will
       cause your server to become part of large scale DNS amplification
       attacks. Implementing BCP38 within your network would greatly
       reduce such attack surface
    */
    recursion yes;
            dnssec-enable yes;
    dnssec-validation yes;

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

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

    pid-file "/run/named/named.pid";
    session-keyfile "/run/named/session.key";

};

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

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

zone "bazim.ir" {
 type master;
 file "bazim.ir";
 };

include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";

и этот файл моей зоны в /var/ named/bazim.ir :

$ttl 38400
bazim.ir. IN SOA bazim.ir admin.bazim.ir.(
 2; Serial
 10800; Refresh
 3600; Retry

bazim.ir. IN NS ns1.bazim.ir.
bazim.ir. IN NS ns2.bazim.ir.
bazim.ir IN MX 10 mail.bazim.ir.

, когда я запускаю named. service я получаю этот журнал ошибок:

Jul 23 12:51:19 bazim.ir bash[19430]: _default/bazim.ir/IN: extra input text

, и я не понимаю ошибку _default / bazim.ir / IN: extra input text . что означает эта ошибка?
