SEND EMAIL MTA - Anybody know

[#[B]lack]

I am having difficulty sending email by mta someone has a functional code

[Investor]

function sendMail(to, from, title, body)
  local function callbackfnc(result, msg)
    outputDebugString("callbackfnc: " .. result .. " (" .. msg .. ")")
  end
  
  callRemote("https://domain.tld/path/to/file.php", callbackfnc, to, from, title, body)
end

<?php
  include("mta_sdk.php");

  if ($_SERVER['SERVER_ADDR'] != $_SERVER['REMOTE_ADDR']) {
    mta::doReturn(-1, "Remote access not allowed");
    exit;
  }

  $input = mta::getInput();
  if ( isset($input[0]) &&
       isset($input[1]) &&
       isset($input[2]) &&
       isset($input[3])    )
  {
    $to = $input[0];
    $from = $input[1];
    $subject = $input[2];
    $message = $input[3];
    $headers = "From: " . $input[1];
    mail($to, $subject, $message, $headers);
    mta::doReturn(0, "Success");
  }
  else
  {
    mta::doReturn(-1, "Invalid input");
  }
?>

And you need the PHP SDK (mta_sdk.php file) downloadable here: http://code.opencoding.net/mta/mtaphpsdk_0.4.zip

This does not filter against malicious inputs, so make sure you never callRemote to the PHP file with unsanitised user input, or even better, don't use user input at all if possible (except the to email address I suppose)
