Centos7 - Postfix 3.4.7 version 3.8.1 upgrade?

[imlemeciz]

I am running the following code over ssh. postconf mail_version


the result shows mail_version = 3.4.7 as i understand this is the postfix version..


I want to upgrade to Postfix 3.8.1. The postfix-3.8.1.tar.gz file exists. How can I upgrade this version now?

Can you please explain in detail

Upgrading it outside of yum will break CWP links.
