What should be my host name?
I will be hosting my site on a Ubuntu 14.04 OS on my droplet.
I will also be hosting my mail server later.( I’ll be using gmail for business actually.
Some say that your hostname should be Fully Qualified Domain Name if you are going to setup a mail server later.
So should I keep my hostname as abc.com or www.abc.com ( FQDN) ?
And also is it true that droplet’s hostname can’t be changed later?
I am new to this stuff . Please guide me.
