Thank you for advice. But the more I read the docs, the more I do not understand this feature. Sorry.
In my case, postfix-in and postfix-out is one instance. I already have 2 postfix with identical configuration on separate servers. I need to create +5 or more postfix servers with same identical configuration. To economy I want to do it on one server. My steps: 1. I create null-client 2. I create 5 instances 3. Configure the instance. What is the main difference between the configuration of my existing servers, except inet_interface? In my case, inet_interface of each instance will be unique ip address for receive and send mails.
