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?
