Hi I currently run mailcow on a cloud vm at Hetzner with IPv4 and IPv6 address.
I am planning to migrate to a ipv6 only VM on my proxmox cluster. Are there any known issues running mailcow with a static ipv6 address only?
I was experiencing with other modern applications issues with IPv6 only setups so I would be sure that there are now known issues with that on mailcow.
