Detecting Bounced Email

[TalkVirginia]

I'm working on an addon and one of the features is that I'm trying to detect and trap bounced emails. I found a tutorial that walks through setting this up at the following page:

I'd like to run the following script on my shared host, but I'm not sure what vBulletin scripts I would need to include to allow me to add information from the bounced emails into my vbulletin database log table. Any suggestions?

PHP Code:


#!/usr/local/bin/php -q
<?php

// Reading in the email
$fd = fopen("php://stdin", "r");
while (!feof($fd)) {
  $email .= fread($fd, 1024);
}
fclose($fd);

// Parsing the email
$lines = explode("\n", $email);
$stillheaders=true;
for ($i=0; $i < count($lines); $i++) {
  if ($stillheaders) {
    // this is a header
    $headers .= $lines[$i]."\n";

    // look out for special headers
    if (preg_match("/^Subject: (.*)/", $lines[$i], $matches)) {
      $subject = $matches[1];
    }
    if (preg_match("/^From: (.*)/", $lines[$i], $matches)) {
      $from = $matches[1];
    }
    if (preg_match("/^To: (.*)/", $lines[$i], $matches)) {
      $to = $matches[1];
    }
  } else {
    // not a header, but message
    break;
    // Optionally you can read out the message also, instead of the break:
    //$message .= $lines[$i]."\n";
  }

  if (trim($lines[$i])=="") {
    // empty line, header section has ended
    $stillheaders = false;
  }
}

list($part1,$dum1) = explode("-bounce@yoursite.com", trim($to) ); 
list($dum2,$user) = explode("user-", $part1);
//
// $user now contains the user id "12345" in the example
//
// Here you put in your custom code 
// like open up your database connection and 
// mark the user as invalid email address,
// so you don's send to him again.

return true;
