My /etc/crontab file includes the line
*/5 * * * * librenms /opt/librenms/services-wrapper.py 1
I believe that this polls the services every 5 minutes. It also generates an email every 5 minutes to say that it has done so! I looking for guidance on how to stop these emails.
I’m been tweaking my email ISP settings to try and filter out these emails, but was hoping that there has some flag somewhere that would stop the emails being generated.

Other info
I’m using msmtp as a simple sendmail-like tool to forward all emails to my ISP email server. If there isn’t a flag to stop generating the emails, then I’m considering writing a wrapper to try and filter out the CRON messages at that stage.
I’m a hobbyist with a growing collection of home-automations bits which i want to monitor. I’m fairly new to LibreNMS, previously have tried Icinga2 and Zabbix.
Thanks
