最佳解决办法：用PHPMailer和看到他们的各种例子。如果您仍然想要坚持使用您的代码，则需要修改您的headers并添加内容类型：

$headers = 'MIME-Version: 1.0' . "\r\n"; 
$headers .= 'Content-type: text/html; charset=utf-8' . "\r\n"; 

$headers .= 'From: '.$email_from."\r\n"; 
$headers .= 'Reply-To: '.$email_from."\r\n"; 
$headers .= 'X-Mailer: PHP/' . phpversion();
