Hi, first post here and a simple one I guess too.

www.rockfizz.com

The contact page at the bottom of the homepage is as far as I can see configured correctly. However, the error code in the JS displays $('#success > .alert-danger').append("<strong>Sorry " + firstName + ", it seems that my mail server is not responding. Please try again later!");

I will post the JS, HTML and PHP below to illustrate my resources

HTML Code:
     <!-- Contact Section -->
    <section class="contact" id="contact">
        <div class="container">
            <div class="row">
                <div class="col-lg-12 text-center">
                    <h2>Contact me</h2>
                </div>
            </div>
		<div class="contact-form">
            <div class="row">
                <div class="col-lg-8 col-lg-offset-2">
		
                    <form name="sentMessage" id="contactForm" novalidate action="contact_me.php" method="post">
                        <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>

                            </div>
                        </div>
                        <div class="row control-group">
                            <div class="form-group col-xs-12 floating-label-form-group controls">

                        <div class="row control-group">
                            <div class="form-group col-xs-12 floating-label-form-group controls">

                                <p class="help-block text-danger"></p>
                            </div>
                        </div>
                        <br>
                        <div id="success"></div>
                        <div class="row">
                            <div class="form-group col-xs-12 text-center">

                            </div>
                        </div>
					</form>
				</div>
			  </div>
			</div>
        </div>
		
    </section>
Javascript can be viewed here : www.rockfizz.com/contact_me.js

PHP Code:
<?php

error_reporting
(E_ALL);
ini_set('display_errors'1);

// 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 "hello@rockfizz.com";
$email_subject "Rock Fizz:  $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@rockfizz.com\n";
$headers .= "Reply-To: $email_address";    
mail($to,$email_subject,$email_body,$headers);
return 
true;            
?>

Any help or assistance would be greatly appreciate.
