Second mail : "Undelivered Mail Returned to Sender"

[dvb91]

Hi,

I am using a cluster with 3 nodes (Proxmox VE 8.2.4). I added external SMTP, to send mails via my provider. After every backup, I received a "backup successful" mail -> This part is OK.

Unfortunately, I always receive a second mail "Undelivered Mail Returned to Sender", with an older date. Example for this morning. 3 mails OK, but 3 issues "Undelivered..." :


When I check one of "Undelivered..." mails, date of sending is a few days old -> 27 jui.



Could you please help me to find the problem ?
Maybe I missed something in settings.

Thanks.

After a fresh install (upgrading hw) , problem's gone. Probably a bad setting.
Sorry for the inconvenience caused by this post.

I have this too! But it goes too far for me to reinstall.
My configuration is two nodes and a qdevice. The two nodes are identical hardware and settings… or so I think. Though apparently there’s something different.

What is you pveversion -v and the contents of /etc/pve/notifications.cfg?

I receive the emails about garbage collection and verify jobs and the vzdump backup status. But the last one only for pvegrey node. A few days later the email of pveblue is forwarded that it couldn’t be delivered.
