Package: mimedefang Version: 2.84-1 To test the systemd changes of mine that you merged, and to update mimedefang generally, I rebuilt 2.84-1 in a PPA for Ubuntu 16.04. This bug could be Ubuntu-specific, but the fix seems safe anyway.
Installation failed with this: mkdir: cannot create directory ‘0700’: Permission denied mkdir: cannot create directory ‘/var/spool/MIMEDefang/.spamassassin’: File exists The runuser command in the postinst failed because runuser has a -m option, so it was interpreting mkdir's option as its own. The fix is to add -- after the runuser options in mimedefang.postinst: runuser -u defang -- mkdir -p -m 0700 /var/spool/MIMEDefang/.spamassassin -- Richard
