How to stop some of the cron frequent jobs from sending e-mail and filling up Your inbox?
/dev/null them.
How? Add this after the command:
>/dev/null 2>&1
so Your task looks lets say like this:
*/5 * * * * /path/to/executable >/dev/null 2>&1
This way the executable will be ran every 5 minutes but You won’t receive any emails about it.
Cheers.
