I read through the "Multi Instance ReadMe" and didn't see an answer for my question so I thought I'd just ask.
When I specify a configuration in the default instance of Postfix that setting seems to be inherited by the other instances. For example: I set message_size_limit on the default instance and I didn't specify a message_size_limit on an additional instance. When I check postconf on the non-default instance I can see that the message_size_limit is set to the value of the default instance. I think this is great. I love being able to set things like message_size_limit once instead of per instance. So is this kind of configuration recommended? Or is it better to specify all settings in each instance? Thanks
