I have created a container on my Proxmox and installed Mailinabox in it.
Now Mailinabox is supposed to manage all emails from Proxmox.
As an an example.
On my Proxmox fail2ban is running
I now want the fail2ban email me as soon as something happens.
How do I set this up?
What do I have to consider with DNS?
Where do I manage the DNS? at Namecheap or in Mailinabox
