I use a hosted email security as front end to SMTP
If I want to use the SMTP proxy.
How do I set the SMTP prox to allow only these 216.99.131.0/24 , 216.104.4.0/24 , 150.70.149.0/27 IP ranges and block all others.

I think
I set the "whitelist clients" for
216.99.131.0/24
216.104.4.0/24
150.70.149.0/27

but what do I set in the "blacklist clients" to stop all the others.

Or is the setting something else.

What about only opening port 25 for those IP's in the firewall ?

Edit: Doesnt seem to work with the buildin smtp proxy.

Thank I have been using a port forwarding rule on port 25 incomming  but I wanted to see the mail in the GRAPH logs ....

I have set the blacklist to 0.0.0.0/0 and it seem to be working now for now through the proxy.

The mail server is also only allowing these IP addresses.
