I have an email server with pmta. Someone recommended me to follow this link for IP warmup in order to not get blacklisted. I am using mailwizz with 7 IPs.

I tried to set the delivery servers via /etc/pmta/configand changing the config file by adding max-msg-rate 25/h.

I then reset /etc/init.d/pmta restart

I tried again but it is still exceeding the limit

Is there anything I did wrong?

max-msg-rate 25/h is a domain scoped directive, so you would need to apply this to each domain that you send to and <domain *>. I'm not sure about that directive specifically, but some require a reload and not a restart for the configuration change to take effect (specifically adding/changing the admin access IP for the PowerMTA web monitor).

You have to make a macro as the follow:

<domain *>
    max-smtp-out 5
    max-msg-per-connection 20
    max-msg-rate 10000/d 
    bounce-after 12h
</domain>

For warming up you have to use the following delivery parameter 

cold-virtual-mta [virtual-mta-here]
    <domain *>
        max-cold-virtual-mta-msg 1000/day
    </domain>
