Mail and DNS
Suppose i have a mail server "my-site.com" .
I need to give entry this Domain into my "DNS Forward Zone" Like followiong way :
@ IN SOA ns1.my-site.com. hostmaster.my-site.com. (
200211152 ; serial#
3600 ; refresh,
3600 ; expire, seconds
3600 ; retry, seconds
3600 ) ; minimum, seconds
NS www ; Inet Address of nameserver
my-site.com. MX 10 mail; Primary MX
Now A client has offered me to make a different Domain Like "example.com" and they need also a Mail server . i.e., Here i need to make Two server One is "DNS" and A Mail server .
In this moment i have two questions :
1) Is it necessary to make a different DNS server in different machine ? If it is not how can i make this Domain / DNS ?
2) Is it necessary to make a different Mail Server in different Machine ? If it is not how can do it ?
Plz provide some Information .. I am new to use Mail server .
