更改DNS后，PHP联系人表单不再工作

我让我的网站通过这个渠道托管自己的DNS记录和邮件帐户。但是，我将电子邮件托管迁移到fastmail，现在通过它们托管DNS，并有一个指向我的web托管服务器IP的记录

由于更改此设置，我主页上的联系人表单已损坏。我将附加php代码

 <?php
// Check for empty fields
if(empty($_POST['name'])        ||
   empty($_POST['email'])       ||
   empty($_POST['phone'])       ||
   empty($_POST['message']) ||
   !filter_var($_POST['email'],FILTER_VALIDATE_EMAIL))
   {
    echo "No arguments Provided!";
    return false;
   }

$name = $_POST['name'];
$email_address = $_POST['email'];
$phone = $_POST['phone'];
$message = $_POST['message'];

// Create the email and send the message
$to = 'i did put my real email here.'; // Add your email address inbetween the '' replacing yourname@yourdomain.com - This is where the form will send a message to.
$email_subject = "Website Contact Form:  $name";
$email_body = "You have received a new message from your website contact form.\n\n"."Here are the details:\n\nName: $name\n\nEmail: $email_address\n\nPhone: $phone\n\nMessage:\n$message";
$headers = "From: noreply@yourdomain.com\n"; // This is the email address the generated message will be from. We recommend using something like noreply@yourdomain.com.
$headers .= "Reply-To: $email_address"; 
mail($to,$email_subject,$email_body,$headers);
return true;            
?>

HTML代码：

<form name="sentMessage" id="contactForm" novalidate>
                        <div class="row control-group">
                            <div class="form-group col-xs-12 floating-label-form-group controls">

我认为它现在一定不能正确地发送邮件，或者从web主机端发送一些东西。感谢您的帮助

编辑：我的网络主机建议使用SMTP，但我不知道它们的意思。

邮件似乎未启用。如果他们希望您使用SMTP，他们可能不允许他们的Web服务器发送电子邮件

您可以使用PHPMailer使用另一个smtp服务器，请参阅

将smtp服务器更改为您可以使用的服务器（询问您的提供商）。
