You need to change your script to send the email itself. I have many
scripts that email reports, legs, and html reports. To accomplish this I
have my cron job run a script like this (I have simplified the script you
should be able to use it as a base):
#!/usr/local/bin/ksh
# set full paths for all commands needed, and files needed
MAIL=/usr/bin/mail
MAILFILE=/tmp/mail_file
#fill in your correct email or alias you wish to use
MAILTO=me@mydomain.com
RM=/bin/rm
DATE=/bin/date
AWK=/usr/bin/awk
LS=/bin/ls
GREP=/usr/bin/grep
FIND=/usr/bin/find
TODAY=`$DATE +%m-%d-%Y`
REPORT_LOG_HEADER=/usr/local/etc/report_log_header
REPORT_LOG_FOOTER=/usr/local/etc/report_log_footer
# start the mailfile with the proper header,
# in this case it is an HTML header
cat $REPORT_LOG_HEADER > $MAILFILE
#put more stuff into the report . . .
echo " " >> $MAILFILE
echo " " >> $MAILFILE
# Add any processing or log files to the middle of the mail file here
# you can even put HTML codes in here
echo "<BR> <BR>" >> $MAILFILE
echo " " >> $MAILFILE
# add the correct HTML footer
cat $REPORT_LOG_FOOTER >> $MAILFILE
# send it to yourself
$MAIL -s "the report name" $MAILTO < $MAILFILE
$RM $MAILFILE
