title: Having difficulties with Notifications.sendEmail from the Facebook API using PHP
body: <p>I'm trying to send an email through the Facebook API. I've added the application and given it the email extended permission. I've been following the instructions at <a href="http://wiki.developers.facebook.com/index.php/Notifications.sendEmail" rel="nofollow noreferrer">http://wiki.developers.facebook.com/index.php/Notifications.sendEmail</a> and am using their sample code (albeit with correct userids in place of the ones they list):</p>
  
  <pre><code>$uids = array(12345,67890,13579);
  $csv = implode(",", $uids); 
  $result=$facebook-&gt;api_client-&gt;notifications_sendEmail($csv,"Test: this should appear in the subject", "This should appear in the body (plain text)", "Test: &lt;b&gt;&lt;i&gt;&lt;u&gt;this should appear in the body&lt;/u&gt;&lt;/i&gt;&lt;/b&gt; (HTML)");
  echo "sent to $result targets of ". count(str_getcsv("$csv",",")) . "total.";
  </code></pre>
  
  <p>The api call returns no errors, but $result is empty indicating none of the emails were sent (confirmed by the emptiness of my inbox). I have tried this in and out of sandbox mode. Asking facebook for contact_email, proxied_email, and email, all return correct results. Attempting to send an email to the address returned by proxied_email does NOT result in an email being received. </p>
  
  <p>I've also tried sending normal notifications and adding news items to the dashboard, both of those work without problem. I'm not sure what application setting or configuration I am missing. Any suggestions for troubleshooting would be very much appreciated.</p>
