mailing list php

[ty7]

AIUTO!
Devo consegnare un sito entro l'una e non mi funziona la mailing list!
Ho scaricato lo script 4_mail_list e modificato leggermente i file, principalmente ho messo il testo in italiano.
Nella mia cartella ho 3 files:
- mailinglist.php
- subscribe.php
- emails.txt (file di testo che memorizza gli indirizzi)

Il codice di mailinglist.php è:
<?
// Some variables;
// Your emails list file;
$filelist = "emails.txt";
// Email headers that subscribed users see
// when you send them an email;
$adminmail = "leslie@caricia.com";
$emailheaders = "Da: " . $adminmail . "\nRispondi a: " . $adminmail;
// By default we display entries;
if (!isset($mode))
   $mode = "unknown";
   
// Since all administration is in one file,
// we choose what to to do now;
switch ($mode) {
       case "create": createList(); break;
       case "display": displayEntries($filelist); break;
       case "add": addEntry($email); break;
       case "edit": displayEditForm($id); break;
       case "doEdit": editEntry($email, $oldvalue); break;
       case "delete": deleteEntry($id); break;
       case "send": sendNews($subject, $message); break;
       default:
       if (file_exists($filelist)) {
          displayEntries(); displayAddEntryForm();
       }

}



/* THIS IS THE PART WHERE WE CREATE A MAILING LIST FILE AUTOMATICALLY */
/* IGNORE IT IF YOU HAVE CREATED IT MANUALLY (NOTHING WILL BE DISPLAYED */
if (!file_exists($filelist)) {
   echo "<form name=createFile action=mailinglist.php method=post>";
   echo "<input type=submit name=mode value=Crea file mailing list>";
   echo "</form>";
   exit;
}

function createList() {
         $fp = fopen($GLOBALS["filelist"], "w");
         if ($fp) {
            echo "<h2>Mailing list file creata con successo!</h2>";
            echo "" . $GLOBALS["filelist"] . "";
            echo "<meta http-equiv='Refresh' content='1; URL=mailinglist.php'>";
            exit;
