Not receiving update notifications by email

[Taomyn]

I have 3 separate PvE nodes i.e. not clustered all running 8.1.4, but for some reason one of them does not send notifications of updates when the others do even though each time I check the updates are waiting for installation.

The two working hosts were originally running 8.0 and upgraded to 8.1, but the third was installed from scratch with 8.1

I know email is working on them all because the scheduled backups on all three hosts send emails each time they finish running.

I cannot find a /var/log/mail.log to see if there is anything logged, the Notification section of Datacenter are identical, and the email address are root@pam are all the same. There is no sign on my mail server of any connections from this host other than those of the backups and from my test using:

echo "test" | mail -s "[PVE] mails to root are forwarded" root

Any ideas where else to look?

Hello!

What are the contents of /etc/pve/notifications.cfg from the node where the update notifications are not working?

 

[Taomyn]

The file contains

sendmail: mail-to-root
    author Proxmox VE (NED)
    comment Send mails to root@pam's email address
    mailto-user root@pam

matcher: default-matcher
    comment Route all notifications to mail-to-root
    mode all
    target mail-to-root

I tried to find the same file on the older hosts, but they don't have it.

Okay, that looks good so far.
What's the output of journalctl -u postfix@-.service?

These look like the backup and test messages which I received
