postfix force ipv4

Postfix config file main.cf does not include option to force ip4.  I can do it manually but everytime a rebuild the mailserver, my changes disappear.  Is there a template that I can modify?

Looks like there is no one here smart enough to answer the question.

Not as smart as you, obviously! 
Chattr.

.. everytime a rebuild the mailserver, ..

Most people only do this once?

I knew there would be at least one sucker who would swallow the bait.

I agree that most only rebuild once.  But every time you mess with the dkim stuff you have to rebuild.

Heres the long and the short of the problem.  postfix main.cf is MISSING a very important line in the networking settings.  Its supposed to be there and it isnt.   inet_protocols= is completely missing and was the cause of all my email problems on my new centos 8 server.  This is going to cause problems for everyone who is running a server on centos 8.

I dont know who is to blame.  But it needs to be fixed.

Yeah, yeah, should've ignored ya.

The truth is that I have no idea, why not have a problem case to solve it? since it is a failure, and if they solve it, let me know xDDDD
