First, make sure that you include email in the scope of permissions like so:

https://www.facebook.com/dialog/oauth?client_id=595603433841467&redirect_uri=http://127.0.0.1:8000/faceb_login/&scope=email

Next retrieve the oauth token as documented elsewhere. Then, to actually retrieve a person’s email, you can make the following request:

https://graph.facebook.com/1162321772?fields=email&access_token=XXXXXXXXXXXXXXXXXXXXXX...

The documentation for the graph api is here:

https://developers.facebook.com/docs/graph-api/using-graph-api

    You can get  user email address and details in Facebook (Facebook Connect or Graph API)
<?php

require '../src/facebook.php';

$facebook = new Facebook(array(
  'appId'  => '344617158898614',
  'secret' => '6dc8ac871858b34798bc2488200e503d',
));

// See if there is a user from a cookie
$user = $facebook->getUser();

if ($user) {
  try {
    // Proceed knowing you have a logged in user who's authenticated.
    $user_profile = $facebook->api('/me');
  } catch (FacebookApiException $e) {
      echo "FacebookApiException";
    echo '<pre>'.htmlspecialchars(print_r($e, true)).'</pre>';
    $user = null;
  }
}

?>
<!DOCTYPE html>
<html xmlns:fb="http://www.facebook.com/2008/fbml">
  <body>
    <?php if ($user) { ?>
      Your user profile is
      <pre>
        <?php print htmlspecialchars(print_r($user_profile, true)) ?>
      </pre>
    <?php } else { ?>


      <div class="fb-login-button" data-scope="email,user_checkins">
        Login with Facebook
      </div>
    <?php } ?>
    <div id="fb-root"></div>
    <script>
      window.fbAsyncInit = function() {
        FB.init({
          appId: '<?php echo $facebook->getAppID() ?>',
          cookie: true,
          xfbml: true,
          oauth: true
        });
        FB.Event.subscribe('auth.login', function(response) {
          window.location.reload();
        });
        FB.Event.subscribe('auth.logout', function(response) {
          window.location.reload();
        });
      };
      (function() {
        var e = document.createElement('script'); e.async = true;
        e.src = document.location.protocol +
          '//connect.facebook.net/en_US/all.js';
        document.getElementById('fb-root').appendChild(e);
      }());
    </script>
  </body>
</html>

The idea is to get the user's email when he logs in, then store it in your own database for future reference.
