In my case it was a dns / hostfile issue. I had an host-file in place pointing the external domain to an internal ip. That got overwritten by mistake and therefore it (correctly) enforced SPF. Thanks for the help!

Hi, I'm currently having some issues with internal systems that used to work fine. I recently upgraded to Mail Gateway 9.1.0 kernel: 7.0.6-2-pve Now my internal services seem to have troubles sending E-Mails: SMTP Error: The following recipients failed: {USER]@{Domain}.de: <{USER]@{Domain}.de>...

Thanks for finding the upstream patch and the clear explanation. I'm aware of the risks of downgrading, but as Exchange is business-critical I don't see a viable alternative right now. Will keep an eye on the kernel updates and switch back to the latest as soon as the fix lands. I'll mark the...

Hi, Thanks for the suggestion. I applied the recommended args: args: -cpu host,level=30,-hv-time,-hv-stimer,-hv-stimer-direct,-x2apic No change in behaviour – the VM still crashes with DPC_WATCHDOG_VIOLATION on Kernel 7.0.6-2-pve. I ran a trace-cmd record -e kvm during a crash and also...

Thanks for the quick response! The output of AvailableSecurityProperties is: (Get-CimInstance -ClassName Win32_DeviceGuard -Namespace root\Microsoft\Windows\DeviceGuard).AvailableSecurityProperties 1 2 4 5 No 8 in the list, so hardware APIC virtualization does not appear to be active...

I recently ran into a problem that gave me quite a headache, and since I haven't fully resolved it yet, I wanted to share my findings here and ask if anyone has seen something similar. Environment PVE9.2.3, Kernel 7.0.2-7-pve (since 02.06.2026), Windows Server 2025 VM running Exchange SE. VM...

tbh I'm not 100% sure, it's a year later. I believe I had a wrong port forwarding.

Indeed WSUS was still blocking KB5063878. After that I still had BSOD Issues, but at least with another Error Message (kernel). Installing virtio-win-0.1.285 SCSI Drivers helped. Current working config, as it may help others: scsihw: virtio-scsi-single scsi0...

I assumed it could be a SCSI/VirtIO Problem and hoped someone would have means to mitigate this. But if it's a Windows error I will take it there. Thank you.

Hi, I'm currently running a new Server with Proxmox 9 and a single Windows 2025 VM on it, serving as Exchange Server in our Environment. I installed Virtio 0.1.285 SCSI drivers. For Application awarene Backups I'm running Windows Server Backup, which was fine when I tested in the beginning. Now...

Ok, Mistake was not on PMG-Side. It was a broken NAT rule on our firewall.

Hi, I'm currently having issues sending outbound mails. At first I believed it might be an error in my settings, but I restored a known-good backup and the error persists - and doesn't really make sense to me... Log of outgoing mail: 2025-07-08T17:33:28.419565+02:00 mail postfix/smtpd[2570]...

Sorry for re-aliving this topic - but same Problem here. Bayes is allowing clear spam mail every day - but without Bayes the Detection Rate goes down significantly. Since you can train Bayes - is there a way to create a spam-learning Mailbox that user can forward their spam to?

Danke euch, der Thread war gold wert!
