You would use "2>&1" in conjunction with ">/dev/null" if you didn't  
want to get emails from cron, sure. But if you don't redirect stderr,  
then stderr doesn't end up in the mail.

That is, if "periodic monthly" outputs stdout and stderr, and you  
only redirect (with "|") stdout, then you don't get the stderr.  
"2>&1" says, "send output from file-descriptor 2 (stderr) to file- 
descriptor 1 (stdout)". That way the redirection with the pipe  
contains both stdout and stderr.

As far as redirecting the periodic output to a different user, set  
"daily_output" in /etc/periodic.conf. See /etc/defaults/periodic.conf  
for an example. You'd of course have to do the same for weekly and
