I intend to purchase a domain, say for instance
muppets.org, for my web server and I would like to install Postfix on the same machine for sending transactional emails.
Am I expected to set as hostname for my system
muppets.org, or I can use as hostname
kermit, so that my FQDN can be
According to Digital Ocean's documentation on Postfix, my server's hostname should match my domain,
muppets.org: is that necessary or instead I can use as hostname
kermit and edit
/etc/hosts as follows?
127.0.0.1 localhost.localdomain localhost 127.0.1.1 kermit.muppets.org kermit 198.51.100.3 kermit.muppets.org kermit
