Next question: then what was the purpose of the domain entry box in Leap
15.0 and all previous versions since I remember?

YaST2 - lan @ minas-tirith.valinor

So at some point in time at least it was possible to define the domain name
in yast. Why not now, what has changed? (honest question).
I assume that if the option has been removed intentionally, it is no longer
possible to set it up.

e.g. boo#821599 and boo#1099464

AFAICR postfix as well as sendmail uses gethostbyaddr(3) to ask for the FQDN of
local system for (one or more) of its network device(s).

The resolution depends on /etc/host.conf, /etc/nsswitch.conf, and
/etc/resolv.conf
together with /etc/hosts in the default configuration.

On static network configuration (e.g. with wicked) the FQDNs of the local system
can be added for one or more of its network devices into /etc/hosts.

On a mobile system (e.g. NetworkManager) I'd prefer not do this but let do
the job the NetworkManager and its DHCP part.
