If mailname (the value of /etc/mailname) is supposed to be my FQDN,
then that would be lenin.histomat.net
$ hostname -f
lenin.histomat.net
$ nano /etc/mailname
lenin.histomat.net
True, an MX record refers to a domain name and so I suppose can make
no sense of a domain prepended with a hostname.
So should the value of /etc/mailname be a FQDN or simply a domain
name?
If the latter, then the question is how my installion of the operating
system managed to get it wrong. During network setup I entered the
hostname lenin and domain name histomat.net. Or at least that was
my intention.
In /etc/hosts I have the line:
127.0.1.1 lenin.histomat.net lenin
