Cron/Fetchmail mail

[Edward Dekkers <edward tripled iinet net au>]

This should be simple, but I'm not sure what to search on with google 
(whatever I tried was irrelevant to my situation).

I have put in a crontab:

*/30	*	*	*	*	/usr/bin/fetchmail > /dev/null

This works great unless there are errors, then they are mailed to the 
crontab owner.

Can they be suppressed completely? Even when there's an error?

Regards,
Ed.
