When starting a job via veeamconfig, as it is done in the crontab, it generates output to stdout. In case of a cronjob the result is an email send to the user. I can redirect stdout to /dev/null in the cronjob. Sadly this change gets removed, if the job is altered via veeam.
My suggestion is to add an option to the job configurator, to send normal output to /dev/null.
