Cron sending mail to root

I have a cron job that executes a nightly backup.job listed below.

logfile=/eci/log/Backup.`date | cut -c1-3`
echo Backup began at `date` > $logfile
rm -f /eci/sql/*.dat
tar -cvf /dev/st0 -b 128 /eci >> $logfile
echo Backup ended at `date` >> $logfile

My problem is it mails the information below to root after each job. How can I stop this.

From root Thu Apr 25 22:00:12 2002
Return-Path: <root@localhost.localdomain>
Received: (from root@localhost)

In your crontab file, you probably have the following lines (or similar):

Note the 'MAILTO' line?

<snippet from crontab(5)>
       In addition to LOGNAME, HOME, and SHELL, cron(8) will look
       at MAILTO if it has any reason to send mail as a result of
       running  commands  in  ``this''  crontab.   If  MAILTO  is
       defined (and non-empty), mail  is  sent  to  the  user  so
       named.   If  MAILTO  is  defined but empty (MAILTO=""), no
       mail will be sent.  Otherwise mail is sent to the owner of
       the  crontab.   This  option  is  useful  if you decide on
       /bin/mail instead of /usr/lib/sendmail as your mailer when
       you  install  cron  --  /bin/mail doesn't do aliasing, and
       UUCP usually doesn't read its mail.

Learn to use man -- man is your best friend.

Good luck!
