+#
+# Plugin to monitor incoming Postfix mail.
+#
+# Parameters understood:
+#
+# 	config   (required)
+# 	autoconf (optional)
+#
+
+# requires logtail
+
+# If you are using a postfix policy daemon (such as policyd) to track certain block conditions, place a line
+# in your /etc/munin/plugin-conf.d/munin-node like:
+#
+# [postfix_filtered]
+# env.policy my policy string
+#
+# When env.policy is set, this plugin will match the string you supply as env.policy and return the number of instances
+# of that string as an output called "policy.value". 
+#
+# If you are NOT using a postfix policy daemon, as above, use the line 
+#
+# [postfix_filtered]
+# env.policy none
+#
+# and this plugin will suppress output of policy.value
