Configuring Bind 9 for multiple domain

Question

Hi I am a newbees with Bind I want to hoste multiple domain on the same name server. I'm not sure about my config can you help me ! here's I supposed the public address of the name server is 10.10.10.10 address

here's how I config :

named.conf

options {
     directory "/windows/system32/dns/etc";
     pid-file  "/windows/system32/dns/etc/named.pid";
     recursion no;  
};

zone "aaa.qc.ca" in {
      type master;
      file "db.aaa";
};

zone "bbb.qc.ca" in {
      type master;
      file "db.bbb";
};

zone "ccc.ca" in {
      type master;
      file "db.ccc";
};
zone "0.0.127.in-addr.arpa" in {
      type master;
      file "db.loopback";
};

zone "." {
     type hint;
     file "db.cache";
};

here's my db for each zone

db.aaa

Well, there i no entry for main domain and better make www as CNAME for main domain e.g. for ccc.ca.:

@         IN     A        192.168.0.3
www       IN     CNAME    @

Also, there is no SPF and DKIM entries.
