title: Facebook proxy email not arriving -- do I need permissions?
body: <p>I'm building a website that allows user to connect using Facebook Connect. So far I'm able to log the user in and fetch data about them (name, email, pic, etc.). If I fetch the email (using Users.getInfo) I get a proxied email (apps+blahblah@facebook.com), which is absolutely great. Problem is, that email doesn't work. I've tried sending an email to it and I never received it. There are two reasons I see that could cause this:</p>
  
  <ol>
  <li>I don't have enough permissions. Ok, I can understand that, but if I don't have enough permissions then why are they returning an email at all?</li>
  <li>The email has to be somehow sent from the application itself (I've tried sending it from my Gmail account) -- but how would Facebook know that the email is coming from the application?</li>
  </ol>
  
  <p>So which is it? Or is it something else?</p>
