Packages in EPEL are high-quality add-on packages that complement the Red Hat Enterprise Linux and are prepared for a specific RHEL version. However, you can find rpm package for this tool in EPEL. As of this article in the knowledge base part of Red Hat Customer Portal, https://access.redhat.com/solutions/3358 How to use Extra Packages for Enterprise Linux (EPEL) the EPEL project is led by community-led volunteers, packages from this project are not provided by Red Hat and therefore they are not supported. Closing this bz, I've just cloned it though for addressing in Fedora.
dkim_milter_data_t is defined in selinux-policy, this is not an epel issue. Please reopen and assign to selinux-policy as originally requested.
