Munin contributed plugins

#!/bin/bash

#

# Plugin to monitor spamdyke

#

#    Spamdyke logs expected to be inside /var/log/mail.info

#    logtail must be installed 

#    Plugin state stored in /var/lib/munin/plugin-state

#      (statedir as defined in munin debian packages)

# 

#    You may override spamdyke logfile in plugin-conf.d/munin-node, and

#    give the user/group with enough rights to read your logs (group

#    adm on stock debian works fine)

#

#    [spamdyke]

#    env.logfile /var/log/maillog

#    group adm

#

# 

#

# Parameters understood:

#

# 	config   (required)

# 	autoconf (optional)
