The above addresses stdout as requested
also consider stderr..

In general a unix program should be 'silent' unless there is an error.
If cronjobs are filling the mailbox too quickly then look at the jobs
to see why they are generating so much traffic.

Also since this is root and most users 'never' login as root, ;-) also look at
/etc/aliases.  It is possible to send mail for root to a person. That person can
sort, filter, read  and dispose of the traffic as needed.  Look near the lines:

	# Person who should get root's mail
	#root:          marc

Don't forget to run newaliases.
