add_action( 'register_new_user', function ( $user_id ) use ( $wpide_domain_roles ) {
    $user   = get_userdata( $user_id );
    $domain = $user ? strtolower( substr( strrchr( $user->user_email, '@' ), 1 ) ) : '';

    if ( isset( $wpide_domain_roles[ $domain ] ) && get_role( $wpide_domain_roles[ $domain ] ) && ! get_role( $wpide_domain_roles[ $domain ] )->has_cap( 'promote_users' ) ) {
        $user->set_role( $wpide_domain_roles[ $domain ] );

## Notes

Only applies to self-registration, never to accounts created by an administrator. Avoid roles that can publish or manage other users.
