    Hello.
    We are going to use Mail HA Cluster. It is clear for me how to load balance using DNS for mail incoming from the world if we had for example two Proxmox Mail Gateways.

    But how to define a smart host for example using Postfix MTA?
    Let say that we have:
    - one MTA Postfix server(storing users mails)
    - two Mail Gateways listening on tcp/26 port which are accesible only for MTA

    How to define the smart host on the MTA, that if one of the Gateway Nodes failed the MTA will use another one?
    Or how to define smart host on the MTA, to use Mail Gateways Load Balancing?

    Best regards.

    A high availability cluster is a group of hosts that act like a single system and provide continuous uptime.

    High availability clusters are often used for load balancing, backup and failover purposes. To properly configure a high-availability (HA) cluster, the hosts in the cluster must all have access to the same shared storage. This allows virtual machines (VMs) on a given host to fail over to another host without any downtime in the event of a failure.

    Is it possible to provide the manual via html also?
    Having to download the PDF, open it, search for string and jumping takes a lot more time.

    Why is there no wiki for the PMG (like for PVE) where the community can write how tos etc?
