Do keep in mind that on Ubuntu systems Postfix tends to have many
services in master.cf chooted by default, the chroot jail may have
a different /etc/resolv.conf, and may have different copies of
various dynamically loaded nss modules.
Do disable chroot for "smtpd" if enabled, and do test your
getaddrinfo() implementation.
