How can an IP address pool be used to work with the mailing list server (for real subscribers)?

How does UniSender or MailChimp work? Maybe somewhere there are examples.

    probably first of all you are interested in sending letters.

    it is not entirely clear from the question how these ip-addresses are distributed between the machines, so I will briefly present my thoughts on all three options:

    1. several servers, one ip-address per server.

      as far as I understand, the configuration is no different from a single server, except for the number of items in the spf-record.

      load distribution is carried out by the po., sending letters.

    2. one server and several ip-addresses.

      load balancing by means of the smtp server itself. first available articles:

      1. about exim .
      2. about postfix .
    3. several servers, several ip-addresses per server.

      just a combination of the first and second points: load distribution and the means of software sending the letters, and the means of the smtp servers themselves.
