# This script when installed as an hourly cron will look for spam messages
# in a user's Spam folder (see wiki.qmailtoaster.com for --define 'spambox 1')
# and automatically sa-learn from them, and then remove them
# if they are more than 5 days old.
# The 5-day old option can be defined/changed below.
# Portions of this script came from
# Erik Espinoza's <espinoza@forcenetworks.com> pruning script


# Varibale to define how old messages must be before being learned and deleted

# find and process each .Spam directory
# then find and process each file in the .Spam directory
