Selecting auto-create maildirs produces error: Could not make user maildir

After reading the documentation for the mkdir() function, it seems servers with safe_mode on need a tweak around the mkdir() call. Before callking mkdir(), you need to temporarily set umask to zero using umask(0). I revised the code of the _cryptpw_maildirmake() function as follows, and it fixed the problem:

function _cryptpw_maildirmake($maildir) {
  foreach(array('cur','new','tmp') as $d) {
    $old_umask = umask(0);
    if (!mkdir("$maildir/$d",0700,TRUE)) {
      drupal_set_message(
        t('Could not create directory %d.',
          array('%d'=>"$maildir/$d")
        )
      );
      umask($oldumask);
      return FALSE;
    }
  }
}

You might want to include this in the next release....
