Notifications not working on new Cluster Host

[Drallas]

I had to reinstall one of my hosts earlier this week, unfortunatley the new host won't send any notifications for Backup Jobs / SMART.
Via the (new) notification-system SMTP or Discord works fine on my pve01 and pve2 but the third pve03 won't pick it up.



I did verify and the SMART notifications are generated on the third node:

smartd -q onecheck -c /etc/smartd.conf

I carefully read https://pve.proxmox.com/pve-docs/chapter-notifications.html but can't find anything that's off, is there anything special that has to be done on the individual host?

First check if mail could be send from shell otherwise look on your postfix config before searching in pve to problem.

Mail is working on the host 1 and host 2, yet I don't use mail any more but Discord, which is also working on host 1 and host 2! Assuming I don't need Postfix for SMTP mail and or Discord!

Solved: The /etc/aliases.db file was missing!

Recreated it, ran sudo newaliases, and restarted Postfix with sudo systemctl restart postfix.

Notifications from the third host started working immediately.
