The use of $(hostname -i) as on 11.2 very easy breaks postfix, because
it returns a _list_ of IP adresses:
xanthos:~ # hostname -i
172.16.10.1 172.16.1.1
xanthos:~ # grep xanthos /etc/hosts
172.16.10.1 xanthos.mat-home.net xanthos
172.16.1.1 xanthos.mat-home.net xanthos
or more worse, like this:
xanthos:~ # hostname -f
localhost
xanthos:~ # hostname -i
127.0.0.1 172.16.10.1 172.16.1.1
xanthos:~ # grep xanthos /etc/hosts
127.0.0.1 localhost xanthos
172.16.10.1 xanthos.mat-home.net xanthos
172.16.1.1 xanthos.mat-home.net xanthos
Note, that this list can also be very easy empty!
This is the case when you disable to write it with 127.0.0.2 to /etc/hosts
(WRITE_HOSTNAME_TO_HOSTS=no), the hostname update via dhcp is disabled
(DHCLIENT_SET_HOSTNAME) or the dhcp server simply does not provide any, ...
finally it may also happen due to an temporary DNS failure.
Please fix, e.g. using a "for i in $(hostname -i) ; do" loop.
Further, $FQHOSTNAME may be "linux.local" on two hosts (opensuse machines).
I don't think that it is helpful to reject mails with "Liar!" -- in worst
case this is an affront and maybe worth a lawsuit in best case bad style.
