+# NOTE: This is a legacy configuration file. It is not used by the opendkim
+# systemd service. Please use the corresponding configuration parameters in
+# /etc/opendkim.conf instead.
+#
+# Previously, one would edit the default settings here, and then execute
+# /lib/opendkim/opendkim.service.generate to generate systemd override files at
+# /etc/systemd/system/opendkim.service.d/override.conf and
+# /etc/tmpfiles.d/opendkim.conf. While this is still possible, it is now
+# recommended to adjust the settings directly in /etc/opendkim.conf.

+#DAEMON_OPTS=""
+# Change to /var/spool/postfix/run/opendkim to use a Unix socket with
+# postfix in a chroot:
+#RUNDIR=/var/spool/postfix/run/opendkim
+RUNDIR=/run/opendkim
+#
+# Uncomment to specify an alternate socket
+# Note that setting this will override any Socket value in opendkim.conf
