There are some commercial Certificate Authorities that offer free certificates. But in contrast Let's Encrypt is a non-profit.

• ZeroSSL (Austria)
• Actalis (Italy)

Apparently Microsoft is already planning to kill the "new" Outlook with some AI native "new new" Outlook. So don't get used to it too much I guess. Source: https://www.theverge.com/...

You mentioned that you can't ping the remote VM. Have you checked if the remote VMs IP is reachable? Is it in the ARP table? Check with arp -a

I used traefik in the past, but moved to Caddy a while ago. In traefik I had to restart the service to apply the renewed certificate, which I found annoying. Caddy on the other hand just works <- Edit: might be wrong

Anyway, are you using anything by the Linux Foundation?

Thanks a lot! Highly appreciated :)

I haven't tried it yet, but I think you want something like n8n. Yeah, I know they claim to be very AI nowadays, but I had them on my radar before that. It's essentially an automation platform you can use to glue services together that weren't intended for each other. https://github.com/n8n-io/n8n

While Netbird is generally just one of the many alternatives to Tailscale, they also do have a Reverse Proxy feature that allows access without a Netbird client. Haven't tested it yet, seems to be in beta.

Oh, lol! I mean I was totally aware of Kubernetes existing as an enterprise grade container solution, but didn't really consider that it could fit my needs. Makes so much sense that they have a feature like Volume snapshots. Gonna look into Kubernetes/k3s. Thanks!

You could run an individual Immich instance per user. Not sure if it's feasible or smart

Hm... Maybe then I'm confusing it with the cert renewal in Home Assistant.

I'd rather try the mail contact option, should work fine if you create them via PowerShell.

Regarding the Internal Relay option: If you configure a Domain with that option then Exchange Online will accept mails for all addresses with that domain and not send any Non Delivery Reports, because it knows that there are more email systems with that domain. EXO doesn't have the full picture so it has to accept all mails. If there is no internal recipient defined with that mail address the message will get forwarded to an external system that you configured. That 2nd system would need to send the NDR then. Please note: But that configuration would potentially forward more emails than you would want to the external system.
