#!/bin/bash

# 09/11/09 - Eric <ejs@shubes.net>
# changed -ctime to -mtime
# refactored to simplify a bit
#
# 07/06/07 - Jake <jake@v2gnu.com>
# This is a modified version of Erik Espinoza's <espinoza@forcenetworks.com>
# qtp-prune.sh script. It has been modified to be used with the QmailToaster-Plus
# package.  It will delete files in the Trash folders that are older than 5
# days, and can be modified by adjusting the DELTIME variable.
# 
# 23/10/2007 - Davide <buzzz@synhack.it>
# Added the possibility to use an external file to configure the deltrash value
# just put in DELTIME_FILE the path of the file which contain the value 

# default DELTIME value 
DELTIME=5

# config file for deltrash 
DELTIME_FILE="/var/qmail/control/deltrash" 

# see if there is a configuration file for DELTIME

  DELTIME_TMP=`cat $DELTIME_FILE`
  if [ "$(echo $DELTIME_TMP | grep "^[[:digit:]]*$")" ] ; then

# find and process each .Spam directory
# then find and process each file in the .Spam directory
# (this could probably all be done in a single find command)
