function smarty_modifier_email_mask($string, $maskPart = 60, $position = 'center', $maskString = '*') {
    $emailName = substr($string, 0, strpos($string, '@'));
    $emailLen = strlen($emailName);
    $maskNum = floor($emailLen * $maskPart / 100);
    $maskName = '';

    if ($position == 'center') {
