php mail with .js validation -> can't see any mistakes

[IamSuchANoob]

I got this piece of code from a free template and I followed all the instructions that came with it, everything seems fine but mail doesn't go trough. HTML:

<!--Start Contact form --> 
<form name="enq" method="post" action="email/" onsubmit="return validation();">
<fieldset>

<input type="text" name="name" id="name" value="" class="input-block-level" placeholder="Name.." />
<input type="text" name="email" id="email" value="" class="input-block-level" placeholder="Email.." />
<textarea rows="11" name="message" id="message" class="input-block-level" placeholder="Message.."></textarea>
<div class="actions">
<input type="submit" value="Send!" name="submit" id="submitButton" class="btn btn-info pull-right" title="Send!" />
</div>

</fieldset>
</form> 
<!--End Contact form -->

PHP:

<?php
if(isset($_POST['submit']))
{
$name = $_POST['name'];
$email = $_POST['email'];
$query = $_POST['message'];
$email_from = $name.'<'.$email.'>';

$to="[email protected]";
$subject="Enquiry!";
$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$headers .= "From: ".$email_from."\r\n";
$message="

Name:
$name
<br>
Email-Id:
$email
<br>
Message:
$query

";
if(mail($to,$subject,$message,$headers))
header("Location:../contact.php?msg=Successful Submission! Thankyou for contacting us.");
else
header("Location:../contact.php?msg=Error To send Email !");
//contact:[email protected]
}
?>

JavaScript

function validation()
{

var contactname=document.enq.name.value;
var name_exp=/^[A-Za-z\s]+$/;
if(contactname=='')
{
alert("Name Field Should Not Be Empty!");
document.enq.name.focus();
return false;
}
else if(!contactname.match(name_exp))
{
alert("Invalid Name field!");
document.enq.name.focus();
return false;
}

var email=document.enq.email.value;
//var email_exp=/^[A-Za-z0-9\.-_\$]+@[A-Za-z]+\.[a-z]{2,4}$/;
var email_exp=/^\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$/;
if(email=='')
{
alert("Please Enter Email-Id!");
document.enq.email.focus();
return false;
}
else if(!email.match(email_exp))
{
alert("Invalid Email ID !");
document.enq.email.focus();
return false;
}


var message=document.enq.message.value;
if(message=='')
{
alert("Query Field Should Not Be Empty!");
document.enq.message.focus();
return false;
}
return true;
}

I don't get any errors but mail doesn't simply go trough, checked spam etc.

Was probably mailserver... works like a charm on another host. Close please.
