PHP联系人表单在更改DNS后不再工作

Question

我的网站通过通道托管了自己的DNS记录和邮件帐户。然而，我将电子邮件托管迁移到了fastmail，现在通过它们托管了DNS，并有指向我的网络托管服务器IP的A记录。

由于更改为此设置，我主页上的联系人表格已损坏。我将附上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 [e-mail] - 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.nn"."Here are the details:nnName: $namennEmail: $email_addressnnPhone: $phonennMessage:n$message";
$headers = "From: [e-mail]"; // This is the email address the generated message will be from. We recommend using something like [e-mail].
$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">
                                <label>Name</label>
                                <input type="text" class="form-control" placeholder="Name" id="name" required data-validation-required-message="Please enter your name.">
                                <p class="help-block text-danger"></p>
                            </div>
                        </div>
                        <div class="row control-group">
                            <div class="form-group col-xs-12 floating-label-form-group controls">
                                <label>Email Address</label>
                                <input type="email" class="form-control" placeholder="Email Address" id="email" required data-validation-required-message="Please enter your email address.">
                                <p class="help-block text-danger"></p>
                            </div>
                        </div>
                        <div class="row control-group">
                            <div class="form-group col-xs-12 floating-label-form-group controls">
                                <label>Phone Number</label>
                                <input type="tel" class="form-control" placeholder="Phone Number" id="phone" required data-validation-required-message="Please enter your phone number.">
                                <p class="help-block text-danger"></p>
                            </div>
                        </div>
                        <div class="row control-group">
                            <div class="form-group col-xs-12 floating-label-form-group controls">
                                <label>Message</label>
                                <textarea rows="5" class="form-control" placeholder="Message" id="message" required data-validation-required-message="Please enter a message."></textarea>
                                <p class="help-block text-danger"></p>
                            </div>
                        </div>
                        <br>
                        <div id="success"></div>
                        <div class="row">
                            <div class="form-group col-xs-12">
                                <button type="submit" class="btn btn-success btn-lg">Send</button>
                            </div>
                        </div>
                    </form>

我想它现在一定没有正确地发送邮件，或者是从网络主机端发送了什么。感谢您的帮助。

编辑：我的网络主机建议使用SMTP，但我不知道它们是什么意思。

Answer 1

看起来邮件没有启用。如果他们希望你使用SMTP，他们可能不允许他们的网络服务器发送电子邮件。

您可以使用PHPMailer来使用另一个smtp服务器，请参阅此链接。

将smtp服务器更改为您可以使用的服务器（询问您的提供商）。
