    Block All Outgoing IP addresses

    Stoiko Ivanov Tnx for answer. If I understand correctly, the rule BLOCK without "who-object" applied for all messages? Then this is my solution.

    Block All Outgoing IP addresses

    Hello All! I want to block all connections for outgoing mail except IP in whitelist. I have created whitelist, but I can't understand how is block all another IP. Proxmox doesn't allow set mask to IP in the blacklist rule. Or maybe I will be able disable local network for access by default?
