linux - What is the point of adding "IP domain.tld" to the ( /etc/hosts ) file if the server is not gonna be used as a mail server? -

-

for domain name work.. it's dns servers need point correct ip.

once domain tries connect ip

the server uses apache configuration determine domain based on in 

<virtualhost *:80> </virtualhost>

for servername, serveralias etc.

so if decide not set mail server, never have bother adding

ip domain.tld

to /etc/hosts file ?

i suppose /etc/hosts file needs ip domain.tld if there mail server setup?

/etc/hosts file alternative dns host name resolution. has nothing mail servers. but, use mail server has found on network.

/etc/hosts local lookup file computer uses specified in /etc/nsswitch.conf.

dns network service provided each domain. example, bind. domain zone files configured , hosted on domains primary dns servers.

you can configure domain searches in /etc/resolv.conf.
