I've been intensively working with Proxmox MG over the past few days and found the documentation not always helpful.
My spam has been reduced by 95%, and I would like to explain here what I changed compared to the out-of-the-box installation to achieve this. From my perspective, this is something that is insufficiently covered in many guides.
Thanks to the Proxmox team for this excellent product and thanks to everyone whose comments and recommendations I implemented. Feel free to comment — if you like this post, leave a subscription and a like … just kidding.
