#
# 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
