In my setup I have installed virtualmin for virtual servers. I have following virtual servers with their own dedicated ip address. Postfix is configured as per this method to use dedicated ip for each virtual server.
Virtual server 1 (ip = 18.104.22.168) = example.com virtual server 2 (ip - 22.214.171.124) = example2.com virtual server 3 (ip = 126.96.36.199) = example3.com
My postfix setting in virtualmin already setup to use virtual server's own ip to send emails. My question is, how to setup following rules of postfix per virtual server.
smtp_destination_concurrency_limit = 2 smtp_destination_rate_delay = 1s smtp_extra_recipient_limit = 10
I did not find any configuration like above for per virtual server / per ip rate limiting.
