#
# Plugin to monitor the amavis mail filter for Debian
# (based upon a plugin authored by Geoffroy Desvernay)
#
# This plugin is built and tested on Debian Etch using:
# munin 1.2.5-1
# amavisd-new 2.4.2-6.1
#
# With some minor modification it should also work on non-debian systems
# This, however, is up to you
#
# Munin graph will sum up: Passed CLEAN, Blocked VIRUS, Blocked SPAM, Other
#
# Parameters understood:
# config (required)
# autoconf (optional)
#
# Config variables:
# AMAVIS_LOG - file where amavis logs are written
# STATEFILE - file which is needed to keep track of AMAVIS_LOG
# LOGTAIL - location of logtail
# BC - location of bc
#
# Enjoy!
# Fili Wiese
