Supporting opendkim and opendmarc on RHEL 8

Folks, we use the Satellite servers to serve updates for all our RHEL. The guy who runs these for us specifically tells us that RH recommends against including EPEL repository in the Satellite configuration because of clashes with regular RHEL packages. My problem is that I require the opendkim and opendmarc packages to support our postfix email servers.

So how do I go about getting the opendkim and opendmarc packages without running the risk of causing package clashes between EPEL and RHEL repos?
