php - Submit form with ajax problems -

i having issues message form submission. can information send .php file email not sending can me?

here jquery

$('form.contact').on('submit', function() {    var    = $(this),       url     = that.attr('action'),       type  = that.attr('method'),       data    = {};    that.find('[name]').each(function() {       var = $(this);           name = that.attr('name');           value = that.val();        data[name] = value;   });    $.ajax({       url: url,       type: type,       data: data,       success: function(response) {         console.log(response);       }   });    return false; }); 

and here php

include 'config.php';  // email submit if (isset($_post['email']) && isset($_post['name']) && isset($_post['message'])){     //send email    mail(email_address, "contact form: ".$_post['name'],    $_post['message'], "from:" . $_post['email']);  } 

email_address constant set admin.

and if needed here html

<div id="contact_form">     <form action="admin/submit.php" method="post" class="contact">         <input class="fullwidth" type="text" name="name" placeholder="your name" />         <input class="fullwidth" type="email" name="email" placeholder="email address" />         <textarea type="text" name="message" placeholder="message"></textarea>         <input id="submit" type="submit" value="submit" />         <div id="submit_triangle"></div>     </form> </div> 

well, code seems fine. have mail server installed on system. check settings of mail server if have it

http://php.net/manual/en/function.mail.php says mail returns true if mail accepted delivery, false otherwise.

it important note because mail accepted delivery, not mean mail reach intended destination
