Check /etc/cron.d and /etc/cron.daily for logwatch entries.

Ahh. Thank you I found it in the cron.daily directory: 00logwatch

#!/bin/bash

#Check if removed-but-not-purged
test -x /usr/share/logwatch/scripts/logwatch.pl || exit 0

#execute
/usr/sbin/logwatch --output mail

#Note: It's possible to force the recipient in above command
#Just pass --mailto address@a.com instead of --output mail

Thank you.
