Clarification on Offline PMG Subscription Activation (POM Mirror-Key & Required Commands)

[powersupport]

Hi Team,


We would like to clarify the correct steps for activating Proxmox Mail Gateway (PMG) subscriptions in an offline / air-gapped environment using Proxmox Offline Mirror (POM).


We understand that the general workflow is:

1. On a machine with internet access (“mirror / key-management” node), add/register the POM mirror-key.
2. Register the PMG subscription key + server ID on this same machine.
3. Export the offline key data and apply it on the PMG host using:

proxmox-offline-mirror-helper offline-key --mountpoint <media> --product pmg

We want to confirm the following points:

1. Do we need to generate the POM mirror-key manually?
   If yes, could you confirm the exact recommended steps?
   
   
2. Once the mirror-key is obtained, what are the exact commands to:
   • add/import the mirror-key
   • register the PMG subscription key together with the server ID
     
3. For activating subscriptions on a machine with internet access, does the machine require direct connectivity to: https://shop.proxmox.com
   or any other specific Proxmox endpoints?

We appreciate your guidance so we can ensure our offline activation workflow follows the official and supported method.


Thank you.
