Have you looked at your crontab? do you have a MailTo statement in there that may be your problem.

Thanks for your comments.
I've just tried putting a command which produces error output to the same crontab.
With the redirection "> /dev/null 2>&1" , I didn't get any email from that cron job.
However, mrtg produces mail from error messages.
I am sure that is the specific cron job that mrtg is run, because there is no other crontab of any other user.
I don't know why mrtg produces these. I can't track it also, because the error is not occuring at each run.
Anyway, I installed Cacti running RRDtool. Maybe I'll pass to Cacti.

The OS handles the ooutput of the cronjob - not mrtg.
Maybe someone else who uses CentOS can chime in, but some things to try:
Like I mentioned before, set up a cron job for every 10 minutes to do a LS / > /dev/null 2>&1 Does that get e-mailed?
Are you SURE it's that cronjob? Set up that same job every 10 minutes. Do you get an e-mail every 10 minutes?
Do you have other cron jobs that have output to /dev/null ? Do they get e-mailed also?
Everything I'm seeing on CentOS says
> /dev/null 2>&1
