I always use a wrapper script for mrtg...
#!/bin/sh
LOG=/var/tmp/mrtg.out.$$
rm -f ${LOG}
/usr/bin/mrtg /etc/mrtg/mrtg.cfg > ${LOG} 2>&1
if [ -s ${LOG} ]; then
cat ${LOG} | mail -s "MRTG Report" [EMAIL PROTECTED]
fi
rm -f ${LOG}
And then in cron....
0,5,10,15,20,25,30,35,40,45,50,55 * * * * wrapper.sh > /dev/null 2>&1
