Could it be that here the DNS/FQDN (Fully Qualified Domain Name) is mixed with the static hostname which is given in /proc/sys/kernel/hostname?
The first is bind normally to the first (ether)net device whereas the second is set by systemd-hostnamed.service(8) (compare with man:hostnamectl(1) and hostname(7)). In common practice the names before the very first dot do agree but this is not required. Beside this there also exist YP/NIS domain names which may or may not agree with the DSN domain name.
hostname - show or set the system's host name domainname - show or set the system's NIS/YP domain name dnsdomainname - show the system's DNS domain name nodename - show or set the system's DECnet node name
For any MTA the Fully Qualified Domain Name of the host is the one which (IMHO) should be used as e.g. relay hosts/servers do check for this name.
The value in /proc/sys/kernel/hostname is set by the hostname command of which is contained within the /etc/hostname file. Regards, Dennis -- You are receiving this mail because: You are on the CC list for the bug.
