    Outgoing mail from internal servers rejected with “Relay access denied” in PMG

    PMG is mainly for mailserver to mailserver communication. If you are trying sending mail from non mailservers, send those mails to exchange first. Or https://www.postfix.org/SMTPD_ACCESS_README.html#relay and test.

    Hardware advice (or "questionable Proxmox performance on nice box")

    Disabled power saving states on the Dell? Firmware updated? SSDs are enterprise or desktop versions? I have feeling, you have disk problem, missing virtio drivers in Window VMs etc, but nothing concrete, no VM config/pve versions written. Maybe install netdata and check the problematic time window.

    Test migration stuck

    Nothing spotted yet, because remotes are in production and there is nothing non-standard even on netdata (i can miss something of course). Today 4x test moving real vm 10+200 GB, migration fails for 2nd disk around 17-19/16-17 GB position. Moving via ssh/dd succeeded on the 1st try. Only...

    Mark found message as spam via webGUI?

    That's not possible, because message doesn't exists on PMG after delivering to mailserver. So nothing to scan/learn again.

    Is clustering production-ready on Proxmox VE 8.2.2?

    Don't use 8.2.2. You will have problem install another host with this version. Use last PVE version, now 8.4, or go directly to 9.

    A few questions about Backup

    Filebackup of the host. Especially /etc/pve for pve specific configuration, large part of it is handled by cluster, but something is node dependent (example: certificates). Search forum at least.

    New to ProxMox and stabillity

    Running PVE 9 on DL360/380 Gen 8-10 without problem. You can install rsyslog, attach monitor for kernel dump, maybe there will be something not in journal. It's standard debian anyway. Other thing - firmware, power, etc etc etc.
