CRON not turn off

[edica]

I deactivated all CRON notifications. But I get every 5 minutes two notifications in the email of two cron:

sudo /usr/local/vesta/bin/v-update-sys-rrd
sudo /usr/local/vesta/bin/v-update-sys-queue backup

How do I permanently turn off notifications?

In /etc/ssh/sshd_config
PrintMotd no
PrintLastLog no

I cleaned the file /usr/src/scripts/dymotd

It worked!
