Email function not carrying out correctly - php

Question

Ok so ive worked on this for an hour or so and I've just gone blind to what the issue is. Can someone point out what I need to change to make the below code setup so that email address entered in the form sends an email to my admin email account on my server, lets call it admin#email.com. Below is the html forma nd the php code.
PHP:
<?php
if(isset($_POST['email'])) {
// EDIT THE 2 LINES BELOW AS REQUIRED
$email_to = "admin#email.com";
$email_subject = "Your email subject line";
function died($error) {
// your error code can go here
echo "We are very sorry, but there were error(s) found with the form you submitted. ";
echo "These errors appear below.<br /><br />";
echo $error."<br /><br />";
echo "Please go back and fix these errors.<br /><br />";
die();
}
// validation expected data exists
if(!isset($_POST['first_name']) ||
!isset($_POST['last_name']) ||
!isset($_POST['email']) ||
!isset($_POST['telephone']) ||
!isset($_POST['comments'])) {
died('We are sorry, but there appears to be a problem with the form you submitted.');
}
$first_name = $_POST['first_name']; // required
$last_name = $_POST['last_name']; // required
$email_from = $_POST['email']; // required
$telephone = $_POST['telephone']; // not required
$comments = $_POST['comments']; // required
$error_message = "";
$email_exp = '/^[A-Za-z0-9._%-]+#[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
if(!preg_match($email_exp,$email_from)) {
$error_message .= 'The Email Address you entered does not appear to be valid.<br />';
}
$string_exp = "/^[A-Za-z .'-]+$/";
if(!preg_match($string_exp,$first_name)) {
$error_message .= 'The First Name you entered does not appear to be valid.<br />';
}
if(!preg_match($string_exp,$last_name)) {
$error_message .= 'The Last Name you entered does not appear to be valid.<br />';
}
if(strlen($comments) < 2) {
$error_message .= 'The Comments you entered do not appear to be valid.<br />';
}
if(strlen($error_message) > 0) {
died($error_message);
}
$email_message = "Form details below.\n\n";
function clean_string($string) {
$bad = array("content-type","bcc:","to:","cc:","href");
return str_replace($bad,"",$string);
}
$email_message .= "First Name: ".clean_string($first_name)."\n";
$email_message .= "Last Name: ".clean_string($last_name)."\n";
$email_message .= "Email: ".clean_string($email_from)."\n";
$email_message .= "Telephone: ".clean_string($telephone)."\n";
$email_message .= "Comments: ".clean_string($comments)."\n";
// create email headers
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
#mail($email_to, $email_subject, $email_message, $headers);
?>

You don't need any email provider or third party software ON A WORKING SERVER.
I tested the code and it works without problem on server (but shouldn't work on local machine). Do you work locally or on a server? Here's a note from PHP site:
The Windows implementation of mail() differs in many ways from the
Unix implementation. First, it doesn't use a local binary for
composing messages but only operates on direct sockets which means a
MTA is needed listening on a network socket (which can either on the
localhost or a remote machine). Second, the custom headers like From:,
Cc:, Bcc: and Date: are not interpreted by the MTA in the first place,
but are parsed by PHP. As such, the to parameter should not be an
address in the form of "Something ". The mail
command may not parse this properly while talking with the MTA.

OK so after awhile I figured out that i was referencing the wrong email. I was logged into my admin email account on my server and not the user account i created so was not seeing the emails. Stupid enough reason, but working now none the less. Thanks for your help.
