SMTP Configuration + guest crash / shutdown email alerts?

[verulian]

I'm having some trouble getting emails to go out on a Proxmox server. What's the process for debugging SMTP sending issues on Proxmox 6.1?

Additionally, I'm running a few Windows Server installs as guests and one has been having some odd trouble dying on me. The Windows Event Viewer isn't very helpful and I'd like to know where, if any, guest logs may live on Proxmox so I can scrutinize this further.

On top of that, is there a send out an email alert when a guest goes down? And can a restart of a guest be automated such that it will attempt to restart a guest X times if they die within Y minutes of each other?

* check the journal (journalctl -r) for messages from postfix (this should be the MTA if you installed via PVE iso)

most errors should also end up in the journal

no - I would recommend setting up some kind of monitoring system (maybe monit could cover your use-case)

I hope this helps!
