[SOLVED] Notifications configuration on local LAN

[arnoproxmox]

Hi,

Proxmox running fine for a long time.
Now trying to configure notifications via E-mail:

Set mail address of root to root@localhost.
Set mall address of backup job to root@localhost (E-mail (Legacy)-Send Always).
No mail received.

echo "Test mail from postfix" | mail -s "Test proxmox from postfix" root@localhost

Mail received.

echo "test forward proxmox" | /usr/bin/proxmox-mail-forward

No mail received.

How are e-mail notifications configured?
What is the purpose of the E-mail address of user root when mail address is also set in backup jobs?

Now switched to the new notification system. When the next backup job has finished I will see if I got an e-mail.



Setup:
Proxmox installed on top of Debian 12 (GUI installer not used)

pve-manager/8.2.2/9355359cd7afbae4 (running kernel: 6.5.13-1-pve)

PVE and Postfix are on same server

echo "test forward proxmox" | /usr/bin/proxmox-mail-forward

No mail received.

proxmox-mail-forward is invoked by Postfix and is passed the full mail contents, including the headers.

So the following should work:

$ proxmox-mail-forward <<EOF
Subject: Test

this is a test

EOF

How are e-mail notifications configured?
What is the purpose of the E-mail address of user root when mail address is also set in backup jobs?

For backup jobs, there are two ways to receive notifications, the legacy sendmail mode and the new notification system. The notification system was introduced in Proxmox VE 8.1. If you select the legacy mode, the backup job will just use sendmail to send an email configured in the backup job. If you use the notification system, a notification event will be emitted to the notification system where it will be routed based on notification matchers to notification targets. Mail-based notification targets, such as sendmail and SMTP can use the email-address from a user's config as a recipient. Please be sure to check out the chapters on notifications in the Proxmox VE documentation [1] .

Thanks for setting on the right track. Your test worked after changing the mail address of root from root@localhost to root@<hostname>.
Probably a postfix configuration issue (out of scope for here) but at least I receive mail.

Before the change of mail address the backup job showed: INFO: notified via target `mail-to-root`.
No mail.
Let's see if I receive a mail after the next backup job.
Edit: Yes I did.
