Subject: [mrtg] crontab & MRTG emails

Hello,

I'm running MRTG on a Red Hat system, every 5 minutes through cron.

0,5,10,15,20,25,30,35,40,45,50,55 * * * * /usr/bin/mrtg /etc/mrtg/mrtg.cfg

If MRTG experiences any errors (like a host is down) it sends an email
to root.  I would prefer those e-mails to go to someone else.  So I
tried this...

0,5,10,15,20,25,30,35,40,45,50,55 * * * * /usr/bin/mrtg
/etc/mrtg/mrtg.cfg 2>&1 | mail -s "MRTG Report"  someone at domain.com

However, that creates an e-mail EVERY 5 minutes, even if things are
okay.  I am guessing it has something to do with stdout vs stderr. 
Any idea how to structure the cron so I get emails to
someone at domain.com, not root.

Thanks
Shane
