[PVE-User] Where is Install Email Notification Config

[Stefan Radman]

Hi JR

>> It's not in /etc/aliases or any /etc/postfix/* files


proxmox-mail-forward uses the .forward  mechanism to “catch” emails sent to root (or any other user) - see aliases(5).

root at pve:~# cat ~/.forward
|/usr/bin/proxmox-mail-forward
root at pve:~# grep ^user:root /etc/pve/user.cfg 
user:root at pam:1:0:::admin at example.com:::

The user:root at pam entry in user.cfg is where the email address went that you entered during installation.

Lukas Wagner briefly described the mechanism in this <https://forum.proxmox.com/threads/is-the-use-of-proxmox-mail-forward-to-handle-mail-on-pve.133850/post-590618> forum post.

What he described is the legacy mode <https://pve.proxmox.com/pve-docs/chapter-notifications.html#:~:text=legacy%20mode> for sending notification emails.
