IFS=":"

while read username two userid groupid five homedir rest
do
    if [ "$userid" -gt "$USERID_BOUNDARY" ] ; then
       MAILADRES="$username@server.com"
       if [ "du -sm $homedir | cut -f 1" > "$MAXSIZE" ] ; then
           echo "$homedir too big" | /usr/sbin/sendmail $MAILADRES
           echo "test";
