Hi i just need to run a PHP feedback form in my linkstation duo webserver,but it does not send e-mail :(
I know that the html and php code works, but linkstation is unable to send email.

could someone help me how to configure postfix and php.ini settings????

I have done the following steps.

1. I install postfix over SSH using next command "ipkg install postfix".

2. Configure my php.ini mail function.
[mail function]
; For Win32 only.
;SMTP = localhost
;smtp_port = 25

; For Win32 only.
;sendmail_from = me@example.com

; For Unix only.  You may supply arguments as well (default: "sendmail -t -i").
sendmail_path = "/opt/sbin/sendmail -t -i"

; Force the addition of the specified parameters to be passed as extra parameters
; to the sendmail binary. These parameters will always replace the value of
; the 5th parameter to mail(), even in safe mode.
;mail.force_extra_parameters =

here is my feedback html
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<title>Feedback Form</title>   
<h1>Send Us Your Feedback!</h1>
<form action="send_mail.php" method="post">
<td>Email Adress:</td>
<input type="text" name="email_address" value="" maxlength="100" />
<textarea rows="10" cols="50" name="comments"></textarea>
<input type="submit" value="Submit" />

and here is send_mail.php

This first bit sets the email address that you want the form to be submitted to.
You will need to change this value to a valid email address that you can access.
$webmaster_email = "my_own_email@gmail.com";

This bit sets the URLs of the supporting pages.
If you change the names of any of the pages, you will need to change the values here.
$feedback_page = "feedback_form.html";
$error_page = "error_message.html";
$thankyou_page = "thank_you.html";

This next bit loads the form field data into variables.
If you add a form field, you will need to add it here.
$email_address = $_REQUEST['email_address'] ;
$comments = $_REQUEST['comments'] ;

The following function checks for email injection.
Specifically, it checks for carriage returns - typically used by spammers to inject a CC list.
function isInjected($str) {
   $injections = array('(\n+)',
   $inject = join('|', $injections);
   $inject = "/$inject/i";
   if(preg_match($inject,$str)) {
      return true;
   else {
      return false;

// If the user tries to access this script directly, redirect them to the feedback form,
if (!isset($_REQUEST['email_address'])) {
header( "Location: $feedback_page" );

// If the form fields are empty, redirect to the error page.
elseif (empty($email_address) || empty($comments)) {
header( "Location: $error_page" );

// If email injection is detected, redirect to the error page.
elseif ( isInjected($email_address) ) {
header( "Location: $error_page" );

// If we passed all previous tests, send the email then redirect to the thank you page.
else {
mail( "$webmaster_email", "Feedback Form Results",
  $comments, "From: $email_address" );
header( "Location: $thankyou_page" );
