# 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
