I am going through Bind9 to configure DNS server for my domains, but during this process I am confused about points one of them is, when we put email address in zone file do I need to put hostmaster email address with same domain name that I am using in zone configuration file?
For example I have created zone for "example.com". Do I then have to put xxx.example.com in forward zone file or can I put main email in all configurations?
$TTL 86400 @ IN SOA ns1.example.com. myemail.gmail.com ( 20081112001 ; Serial 28800 : Refresh (s) 3600 ; Retry (s) 604800 ; Expiration (s) 38400 ; Negative Cache TTL (s) ) ; @ IN NS ns1 @ IN A 127.0.0.1
