I did some more research and it it the cronjob reporting by email the output of the job (mostly errors, when folder is empty or similar stuff). it will sent the email to the user running or starting the job...in this case "transmission".
because transmission for some reason can not receive the email, the email bounces back to the root account, which in my case forwards it to my "jochen" account...
I then searched how I could disable email reports on errors and found this. It will probably solve my problem:
Code: Select all
Cron Job Prevent the sending of errors and output
To prevent the sending of errors and output, add any one of the following at the end of the line for each cron job to redirect output to /dev/null.
>/dev/null 2>&1.
OR
&> /dev/null
Cron Job Example
Edit/Open your cron jobs, enter:
$ crontab -e
Append string >/dev/null 2>&1 to stop mail alert:
0 1 5 10 * /path/to/script.sh >/dev/null 2>&1
OR
0 1 5 10 * /path/to/script.sh &> /dev/null
Save and close the file. Restart the crond:
# /etc/init.d/crond restart
