[SOLVED] Proxmox send email every one minutes

[Brentz]

Hi all

i receive on system log the below report every minutes:

Aug 28 16:44:02 HV postfix/qmgr[3755]: 28747140F33: from=<root@HV.xxx.lcl>, size=3028, nrcpt=1 (queue active)

Aug 28 16:44:02 HV postfix/qmgr[3755]: 28747140F33: removed

Now if I check the postfix queue it's empty and the mail service is up and running.
Is there a way to know what it's trying to send emails?

thanks in advance

It's right in the logs, it's trying to send a message to "root@HV.xxx.lcl" (and also from that same address) which you probably set as the email-address for the root-account during setup and might just not exist.
Go to the cluster -> users, edit the root user and change their email to an existing email that you can receive these warnings and such on.

Hi @sw-omit and thanks for your reply, but unfortunately it's not that simple. The user is configured correctly and the emails (e.g. backup results) are delivered correctly

Do you see any messages in syslog from the proxmox-mail-forward process?

nothing. I attach the logfile for convenience

You have a cronjob running every minute. By default, cron sends you the commands output via email - see man cron and search for MAILTO

Hope this helps!
