Sendmail and recognized root not dispatching email via chronjob on Ubuntu

I set up the follow cronjob to send security events from Suricata in an email:

Code:#!/bin/bash

tail -n 50 /var/log/suricata/fast.log > "$(date '+%Y-%m-%d_%H-%M-%S').log"

echo "Hello this is the body message, we are sending email with attachement using mutt and msmtp" | mutt -a /home/osboxes/Downloads/"$(date '+%Y-%m-%d_%H-%M-%S').log" -s "this is the subject of the message" -- xxxx@gmail.comThis is the cronjob:

* * * * * sudo su /home/osboxes/Downloads/sendlogzzz.sh


The mutt and msmtp part of the cronjob works fine when I do it manually from CLI just not in the chronjob..

But am running into a problem reflected in syslog:

Code:Apr 19 13:04:01 osboxes CRON[24524]: (root) CMD (sudo su /home/osboxes/Downloads/sendlogzzz.sh)
Apr 19 13:04:02 osboxes cron[497]: sendmail: recipient address root not accepted by the server

logs from auth.log:

Apparmor had been a problem originally so I disabled it.

This is my msmtprc in /etc:

Code:account default
host smtp.gmail.com
port 587
logfile /tmp/msmtp.log
tls on

tls_trust_file /etc/ssl/certs/ca-certificates.crt
