Error notifications and status notifications - email

For Smartdata I found this config which i do hope to add in smartd conf file:

DEVICESCAN -a -o on -S on -n standby,q -s (S/…/…/./02|L/…/…/6/03) -W 4,35,40 -m “my@email”

I am not receiving any emails as the config suggests. Could anyone check what I am missing?
