[SOLVED] Cron keep flooding mail

[Alfagek]

I did used a contab to get the cpu temp.
But when i did used it, i did get flooded with mails from the "postfix" that the crontab was running.
I did try to use the next things in crontab to stop the flooding, but nothing did work:

* * * * * /root/cpu_temp.sh > /dev/null 2>&1

MAILTO= ""

used at the beginning of the crontab, put it behind the line, put it as last line in crontab.

So i changed to a systemctl timer.

So i removed the crontab with crontab -r
But still i get flooded by the postfix with mails:
(

Cron <root@proxmox> /root/cpu_temp.sh > /dev/null

I prefer the contab option, because it works also when my system reboots.

Now i have killed the postfix, so i don't get flooded with mails. But how can i adjust it, so i can use the postfix again without getting flooded with crontab mails.

thanks in advanced.

edit: working version PVE 7.0

This is in my journal, get this every second! (when postfix is enabled)

Why false forum. It’s proxmox related.

But problem is all ready fix.

don’t know for sure what it was. But did make a new crontab and it did work. Only 3 mails, for starting the first time crontab.
