I am using the following script saved as /etc/resolvconf/update.d/postfix: ``` #! /bin/sh
# restart Postfix whenever resolv.conf changes, because Postfix creates # a local copy of the file for use from inside its chroot /usr/sbin/service postfix restart ``` That works reliably when changing network connectivity, e.g. going from cabled Ethernet to WLAN or vice versa. It does not always work during boot. I use Ubuntu 14.04 LTS (and I do not dare to update my work notebook to 16.04 LTS, because it needs to actually work...). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1519331 Title: Postfix cannot resolve DNS if network was unavailable when it was started, such as on a laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/postfix/+bug/1519331/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
