With some help from Ansgar Burchardt, I realized/remembered that the pipe is being created by systemd-tmpfiles in the postinst. Can you try running (as root) # systemd-tmpfiles --create nullmailer.conf The error output of that is redirected to /dev/null in the postinst, but running it interactively should help figure out what went wrong also you might check /usr/lib/tmpfiles.d/nullmailer.conf, it should contain p /var/spool/nullmailer/trigger 622 mail root
