Weekly warning emails with wrong recipient

WD Legacy Products Arkeia Software and Appliances

Hello

each week, I received an unrouted email from my appliance sent from root to an unknown recipient. (undeclared ?)

The subject is “Cron root@srvarkeia /usr/sbin/raid-check”

How can I setup the correct recipient email  ?

What this message means ?

Thanks
