#
# Plugin to monitor Amavis virus and spam statistics.
#
#
# Based on a routine by William Towle
# Uncomment the cdef lines to convert the graph to mails/minute
# Comment out the line "total.graph no" to show the total on the graph. This may not be aesthetically pleasing.
#
# Parameters understood:
#
# 	config   (required)
# 	autoconf (optional)
#

# requires logtail
