Hello forum
Excuse me for my poor English since it's not my primary language.
So I've been working with PVE 6 on my home server; Dell PowerEdge R710.
And since I wanted it to stay quieter, I made a custom script to control fan speed.
To monitor CPU temperature every 10 second, I registered my script in crontab.
It worked find but after about 3 days, I have noticed that /var/log directory was getting really big(about 13GB)
Apon research, I found that same log was being generated every second.
Like this below:

It is just a part of a huge log but rest of the log contains pretty much the same thing.
After some more research, I found that it was crontab that was keep sending email.
So I edited my crontab like below:
* * * * * /bin/sh /root/tempControl/temp_control.sh >/dev/null 2/&1
* * * * * ( sleep 10 ; /bin/sh /root/tempControl/temp_control.sh >/dev/null 2/&1 )
* * * * * ( sleep 20 ; /bin/sh /root/tempControl/temp_control.sh >/dev/null 2/&1 )
* * * * * ( sleep 30 ; /bin/sh /root/tempControl/temp_control.sh >/dev/null 2/&1 )
* * * * * ( sleep 40 ; /bin/sh /root/tempControl/temp_control.sh >/dev/null 2/&1 )
* * * * * ( sleep 50 ; /bin/sh /root/tempControl/temp_control.sh >/dev/null 2/&1 )
to ignore output and error data
but still I'm getting the same log as above and log files like mail.info, mail.warn under /var/log are growing about 1MB per 30 second.
Is there any way to mitigate this issue or to disable email service on proxmox? since I don't need it.
Thank you
