# This script will create an "mbox" format file called "spam.<dirname>"
# in the current directory for each of the directories which are passed
# on the command-line to this script. So you can do
#    cd /var/spool/MailScanner/quarantine
#    df2mbox *
# and it will create a "spam.<dirname>" file in the current directory,
# where each <dirname> is one of the directory names passed on the
# command line. This file will contain all the messages that were
# quarantined in their entirety.
# So if you have
#    Quarantine Whole Message = no
# the only thing in these directories will be spam, not viruses (but
# it will include spam that contained viruses, so be careful!).
#
# Version 1.1 Include date format fix
