Public bug reported:
I'm on 16.04.1 with postfix 3.1.0-3. This is almost exactly the same bug
that has been reported 8-12 years ago, explained in detail here:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=214741#10 ... which is
exactly what I'm experiencing: $mydomain gets set to "localdomain" if my
hostname is a single word (Ubuntu default) instead of a fqdn, unless I
force mydomain=<domain.com> in main.cf
My host+mailname are configured as recommended by Ubuntu, and the
postfix config is pretty default. The above upstream debian bug says it
was fixed in v2.11, but I'm not sure ...
# postconf | grep ^mydomain
mydomain = localdomain
and then in turn:
# postconf | grep ^myhostname
Here are my configs:
# cat /etc/hosts
7x.xx.xxx.100 lin.foodomain.com lin
127.0.0.1 localhost loopback
127.0.1.1 ubuntu
::1 ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
# cat /etc/hostname
lin
# cat /etc/mailname
foodomain.com
# hostname -f
lin.foodomain.com
# postconf -n
