    Just reduce main.cf:default_process_limit so you don'ttry to run
    an insane number of email deliveries in parallel.


I increased that value because I thought that sending more mails in parallel will increase the postfix mail queue delivery....

    There might be
     ways to have multiple queue managers, but ISTR that's kind of
    hackish,
     so you might want to use multiple instances of Postfix instead if you
     go down that path.


Running two separated instance of postfix could be the solution has I have two ips on my server. But I have honestly no idea on how to set that up....
In the main.cf file there is a setting inet_interfaces, you can specify there which IP address to listen to, or even port. You could then run postfix twice using different config files.

    We use the following to restrict concurrency and rate:

    default_destination_concurrency_limit = 2
    default_destination_recipient_limit = 5
    default_destination_rate_delay = 60s


Should I apply does settings on the postfix instance dedicated to newsletter sending? Or should I apply those to my main postfix server?
Yes, that'd be my suggestion anyway.
