# This script requires maildir2mbox, which is part of qmail
#
# It has worked for me for the past 3 months, but I still
# make no guarantees as to its safety. If you wish to use it,
# any loss of mail is your problem and not mine.
#
# I run it from cron as follows:
#
# # Run on the 2nd day of every month (converts/compresses last month's mail)
# 30 04 2 * * /home/seymour/.mutt/zipmail `/home/seymour/.mutt/mailmonth 1`

PATH="/home/seymour/bin:/usr/local/bin:/usr/bin:/bin"
WHERE="/home/seymour/mail"

# What folder of Maildir boxes do we want to process?
# (In my case, which month - ~/mail/2000/08 for example)
if [ -z $1 ]; then
  WHAT=`/home/seymour/.mutt/mailmonth 1`
else
  WHAT=$1
fi

cd $WHERE/$WHAT

echo "Backing up $WHERE/$WHAT:"

for folder in *

  if [ -d $folder ]; then

    # Set up variables for maildir2mbox
    export MAILDIR="$WHERE/$WHAT/$folder"
    export MAIL="$WHERE/$WHAT/$folder.txt"
    export MAILTMP="$WHERE/$WHAT/$folder.tmp"

    # Clean up and compress
