Sending email notifications to all editors the content's editorial section on content state change I am using Using Workbench for content moderation and Workbench Access for access control.

Is it possible to use the rules integration to send an email to all of those users who are in a content node's editorial access control? 

The screenshot shows what I've currently got, which is sending the notification to one particular email address on state change to Needs review.
I don't know what the "editorial access control" is but if you don't find any easier solution you can always write your own rules action for generating the list of people you need. In my case I am sending a message to the reviewers that are provided in one of the fields of the content. It should be easily adaptable to any other porpoise. 

/**
 * Implements hook_rules_action_info().
 */
function mymodule_workflow_rules_action_info() {
  $items = array();
  $items['mymodule_workflow_reviewers'] = array(
    'label' =&gt; t('Get reviewers'),
    'group' =&gt; t('Windbench'),
    'parameter' =&gt; array(
        'node' =&gt; array('type' =&gt; 'node', 'label' =&gt; t('Node')),

    ),
    'provides' =&gt; array(
      'reviewers' =&gt; array('type' =&gt; 'list&lt;user&gt;', 'label' =&gt; t('List of reviewers')),
    ),
  );
  return $items;
}
function mymodule_workflow_reviewers($node){
  $reviewers = array();
  foreach($node-&gt;field_workflow_reviewers['und'] as $reviewer){
    $reviewers[] = user_load($reviewer['uid'],true);
  }
  return array('reviewers' =&gt; $reviewers);
}


And then use that action in your rules
