I think it’s possible to have false-positives. Like [email protected] said above, do a clear and scrub to see if that helps. It happened to me last month after some really intensive disk i/o and AI stuff and I did that and the drive hasn’t had an issue since.

Additionally, I plugged in one of my old, supposedly faulted drives from last year as an external drive on my desktop to test it out, and it is still working fine months later, so yeah, it appears that there is some possibility for false-positives.

Like another person said, make sure you have good backups and that the other drives are solid, but I’d take a wait-and-see approach.

You can use sendgrid to send your emails. That gets around the port 25 problem, but everyone is right - you’ll have a difficult time getting through spam filters even with them.

I selfhost my own email mainly so I don’t have to go through the Google unsecured apps rigamarole every time I want to set up smtp for one of my services, but no one except protonmail gets it reliably.

Proxmox Backup Server. It’s life-changing. I back up every night and I can’t tell you the number of times I’ve completely messed something up only to revert it in a matter of minutes to the nightly backup. You need a separate machine running it–something that kept me from doing it for the longest time–but it is 100% worth it.

I back that up to Backblaze B2 (using Duplicati currently, but I’m going to switch to Kopia), but thankfully I haven’t had to use that, yet.
