Proxmox Cluster - How to manage Postfix configuration accros all nodes, CTs and VMs?

[Dulcow]

Hi there,

A quick question about Postfix configuration: how do you guys manage this effectively within your cluster? Do you have a dedicated container that does SMTP relay and "collect" emails from the rest of the cluster? Do you do it by node? What about CTs and VMs?

I'm running a 9x nodes cluster at home with a few CTs (nothing Production grade). Just curious what people would do in such situation.

Thanks,

D.

Ansible.
No matter how I do it, whether it's a smarthost or each node itself, I have to get to everyone to configure it anyway. Ultimately it runs via a smarthost (Proxmox Mail Gateway) which is then sent.
