Thank you Kris. Thus with "https://wiki.centos.org/HowTos/postfix"; tutorial I'm on a right track and Postfix doen't have any specific options about the selecting record? The Postfix server configured properly and the record option is not related to it?

I *have* met all too many DNS management tools that make bad assumptions about things like this. You should talk to your IT support and/or hosting provider, because both of these are specific to however your DNS records are managed, and neither has anything to do with Postfix configuration. -kgd
