This guide shows how to configure a crontab script to send it's output via email. Thereby that the MAILTO= setting in crontabs is global, it's not that easy to send an email to a different address from another crontab files.

The crontab should then look like this:

/path/to/crontab

#!/bin/bash
RECIPIENT=user@example.com
 
SCRIPT_DIR=$( cd -- "$( dirname -- "${BASH_SOURCE[0]}" )" &> /dev/null && pwd )
SCRIPT_NAME=$(basename "$0")
SENDER=root@$(/bin/hostname)
 
crontab () {
        echo "From: $SENDER"
        echo "Subject: Cron <$SENDER> $SCRIPT_DIR/$SCRIPT_NAME "
        echo "To: $RECIPIENT"
 
	# Commands to be run here
 
        echo ""
        echo "Crontab location: $SCRIPT_DIR/$SCRIPT_NAME"
}
 
crontab | sendmail -t $RECIPIENT
