Yes, what you did with lxc seems to be reproducing the same issue I am seeing.
I am running Yakkety, but I actually did try backporting the package to Xenial and saw the same issue there too. The script that copies the /etc/resolv.conf (and other files) into the chroot is /usr/lib/postfix/configure-instance.sh, which is called as an ExecStartPre in /lib/systemd/system/postfix@.service. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1627117 Title: After systemd integration enabled, Postfix will no longer send mail on startup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/postfix/+bug/1627117/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
