php - php mail（）无法与服务器一起使用

Question

<?php

ini_set('display_errors', '1');
include '../application/includes/config.php';


$mailto=$_POST['email'];
$subject="Information";
$message_body="Welcome to the digital world!";
$from="[e-mail]";


$mail = mail($mailto,$subject,$message_body,"From:".$from);

if($mail){
  echo "Thank you for using our mail form";
}else{
  echo "Mail sending failed."; 
}
?>

我已经在其他网站上测试过这段代码。它在那里工作，但在我的服务器上它只显示“邮件发送失败”错误..
