Hi all,
I can reproduce this on a "stock" openBSD 5.6 with default main.cf (except
for the smtpd_client_restrictions, of course).
/var/spool/postfix/etc/resolv.conf contains
lookup file bind
nameserver 172.16.161.2
and /var/spool/postfix/etc/hosts contains
# $OpenBSD: hosts,v 1.12 2009/03/10 00:42:13 deraadt Exp $
#
# Host Database
#
# RFC 1918 specifies that these networks are "internal".
# 10.0.0.0 10.255.255.255
# 172.16.0.0 172.31.255.255
# 192.168.0.0 192.168.255.255
#
127.0.0.1 localhost
::1 localhost
But NOT on a stock Ubuntu with the same config.
I guess this means that I have to ak openBSD?
cheers
Steven

Yes, BUT:
I had not only postfix in mind. Other server software does not so many
things
right as postfix does. For that reason "general" ...
A server should generally be well configured to use only fully
qualified domainnames.
As a consequence a server does not need a searchdomain in /etc/resolv.conf
and therefor it could be removed.
I do so for many years and saw some strange things went away.
That's simply my experience running numerous different server over the
years.
If some vendor appends domains despite Postfix turning that off,
please file a complaint. That vendor is not helping.
