with proxmox mail gateway is it possible to setup sshd_config without kiling cluster features an stuff etc ?

with those modifications :

PermitRootLogin prohibit-password
PubkeyAuthentication yes
PasswordAuthentication no
PermitEmptyPasswords no

yes this should work, as long as passwordless ssh between the nodes work
you can also install fail2ban to stop brute-force attacks
