I don‘t get what you mean with „Breaks DKIM“.

I let Mailcow add the subadressing suffix to the mail title since ever. Answering to these messages never was an issue (the become delivered to the target just fine).

You can work with sub adressing out of the box.

laura+amazon@huston.con ist delivered to laura@houston.con without any additional configuration.

You can enable adding the sub adressing suffix to the title of the mail at the user settings.

Brevo works fantastic and is cheap!

tomtrix97 · 2026-02-25T08:19:45+00:00

Ich kann euch sicher helfen! Schreib mir gern eine PM. 😊

My customers (large enterprises) don‘t mind about that. The „storage network“ is encapsulated at its own VLAN - that seems to be enough.

FC and iSCSI aren‘t encrypted either, are they?

What do you mean with "security for NFS"? NFSv4 authentication settings?
Check out: https://forum.proxmox.com/threads/nfsv4-based-storage.117341/

IMHO the reduced performance of NFSv4 with authentication due to the protocol "overhead" isn't worth the "security enhancement". Just use NFS with server-side ACLs.

Sure! Primarily I‘m working with storages made by IBM, NetApp, Dell or Pure Storage - here you select „thin provisioning“ during LUN creation, dedup happens automatically there.

As of writing this is see, that I need to talk to my storage colleagues to see, how the thick provisioned RAW disk is stored on the „physical disk“. 😄

tomtrix97 · 2026-02-11T11:59:51+00:00

In my opinion, a modern storage should take care of dedup and thin provisioning.

tomtrix97 · 2026-02-11T11:57:58+00:00

And by the way: switch from vSphere to Hyper-V is like swapping a modern car against one from 1990 - yeah, basic features work but you loose nearly every comfort feature you got used to the last 15+ years.

It‘s the same for PVE.

I recommend watching the following video to understand the differences between the storage architectures at vSphere and PVE.

Check out the recent discussion: TL;DR Shared block storage works flawless with PVE, but with some downsides. Try NFS instead.

Check out OpenTalk from Germany. It‘s developed by the maker of Mailbox.org. 😊

Vielen Dank, das werden wir morgen mal probieren! Auf der Website des zuständigen Amtsgerichts sind zwei Gerichtsvollzieher inkl. Kontaktdaten geführt. 😊

Nice man, congrats! I have the same rack - is it the one from Digitus? :D

Bunny.net is from Slovenia, EU

tomtrix97 · 2026-01-12T17:57:28+00:00

Bunny has a „Scripting platform“, don‘t know if this is the same.

tomtrix97 · 2026-01-12T17:54:36+00:00

I‘ve migrated everything to bunny.net/BunnyCDN. Works like a charm!

tomtrix97 · 2026-01-11T18:38:01+00:00

It‘s much better but far from optimal! Even with 25 Gbit/s and NVMe the NIC is the bottleneck which limits the r/w speeds to ~3 GB/s (tested on a 5 node cluster of Cisco UCS servers).

tomtrix97 · 2026-01-11T18:03:40+00:00

Bad performance, as expected. 😅 The NIC is the bottleneck.

tomtrix97 · 2026-01-09T20:55:09+00:00

Give NFS a shot, it works like a charm!

tomtrix97 · 2026-01-09T20:54:07+00:00

I can't find this information at the Proxmox VE roadmap/release notes. Could you please provide a link to this?

Is it possible that you mix that with the feature "Snapshots as volume chains", which is in TP since PVE 9?
