Core pr 5

Fixed some user redirects and coding style.
The send copy is only available to logged in users, but DDB wants not logged in users to be able to get a copy of the mail.

It's hardcode i Drupal core that only logged in users should be able to this, so no permission is available.

From core:
´´´php
  // We do not allow anonymous users to send themselves a copy
  // because it can be abused to spam people.
  $form['copy'] = array(
    '#type' => 'checkbox',
    '#title' => t('Send yourself a copy.'),
    '#access' => $user->uid,
  );
