Your standard modus operandi should be installing from the CentOS repositories with yum. It is the only thing that is supported and well-tested. It is also the only way to automatically get security updates for Postfix from the CentOS project through yum.
Just on this point, I want to say that I have not seen a security update on postfix in years.
