I got as far as this conclusion too, which got me checking for the
contents of /etc/hosts. Since I can influence the lookup results easily
by shuffling the contents of /etc/hosts, can I conclude that this is an
issue with my glibc?
Example: changing the contents of the hosts file to:
::1 ip6-foobar ip6-localhost ip6-loopback
127.0.0.1 localhost
yields the following result:
postfix/smtpd[5128]: warning: 127.0.0.1: address not listed for hostname
ip6-foobar
