PHP脚本，表单不发送电子邮件

Question

我在使用php时遇到了一些问题。那么，代码，当上传到服务器并在浏览器中运行时，电子邮件正在运行，使用以下代码：

<?php

date_default_timezone_set('Etc/UTC');

require 'PHPMailerAutoload.php';


$mail = new PHPMailer();


$mail->SMTPDebug = 3;
$mail->IsSMTP();
//$mail->IsSMTP();

$mail->Debugoutput = 'html';


$mail->Host = 'relay-hosting.secureserver.net';

$mail->Port = 25;

$mail->SMTPSecure = false;

$mail->SMTPAuth = false;

$mail->Username = "exemple@gmail.com";

$mail->Password = "password";    

$name = "catarina";
$email = "myEmail@hotmail.com";
$message = "test";

$mail->setFrom($email, $name);

$mail->addAddress('me@exemple.io');     

$mail->Subject = 'Contact Site';

$mail->Body = $message;


//send the message, check for errors
if (!$mail->send()) {
    echo "Mailer Error: " . $mail->ErrorInfo;
} else {
    echo "Message sent!";
}

问题是，当我稍微更改此代码以使用表单发送时，电子邮件永远不会到达：

JS：

 function submitForm() {

      $.ajax({type:'POST', url:'email-action.php', data:$('#contact-form').serialize(), success: function(result){
            $('.submit').html('send');
     $('.send').removeClass('no-show');
      $('.send').removeClass('no-show-mobile');
        }});



   }; 

HTML：

 <form action="/" onsubmit="return submitForm();" method="post" name="contactform" class="contact-form wow zoomIn" data-wow-delay="0.6s" id="contact-form">

          <div class="col-md-6">
            <div class="row">
              <div class="col-md-12">

               <input placeholder="Name" class="input-field" name="name" required="" type="text">

             </div>

             <div class="col-md-12">
               <input placeholder="E-mail" class="input-field" name="email" required="" type="email"> 
             </div>
           </div>
         </div>
         <div class="col-md-6">
           <textarea placeholder="Message" class="input-field" name="message"></textarea> 
           <input value="Send Message" class="input-send submit" type="submit" name="submit">
         </div>

         <div class="col-md-12 send no-show hidden-xs"><button class=" botao btn btn-sucess"><h4 class="">Message sent sucessfully! We will get in touch shortly.</h4></button></div>
         <div class="col-md-12 send no-show-mobile visible-xs"><button class=" botao btn btn-sucess"><h4 class="">Message sent sucessfully!</h4></button></div>

</form> 

PHP：        

    date_default_timezone_set('Etc/UTC');

    require 'PHPMailerAutoload.php';


    $mail = new PHPMailer();


    $mail->SMTPDebug = 3;
    $mail->IsSMTP();
    //$mail->IsSMTP();

    $mail->Debugoutput = 'html';

    $mail->Host = 'relay-hosting.secureserver.net';

    $mail->Port = 25;

    $mail->SMTPSecure = false;

    $mail->SMTPAuth = false;

    $mail->Username = "exemple@gmail.com";

    $mail->Password = "password";

///this is the thing that change for one script to another
$name = strip_tags($_POST['name']);
$email = strip_tags($_POST['email']);
$message = strip_tags($_POST['message']);
 /////   
    $mail->setFrom($email, $name);

    $mail->addAddress('me@exemple.io');     

    $mail->Subject = 'Contact Site';

    $mail->Body = $message;


    //send the message, check for errors
    if (!$mail->send()) {
        echo "Mailer Error: " . $mail->ErrorInfo;
    } else {
        echo "Message sent!";
    }
