PHP : un mail qui veut pas venir

Bonjour,

J'ai pas mal utilisé le script de mail qui est proposé ici :

http://www.commentcamarche.net/forum/profil SyGEN

Il marchaiit très bien jusqu'à ce que je veuille le peaufiner un peu dans le script qui va suivre. Résultat : aucun message d'erreur, mais aucun message tout court ! pour tester le fichier directement, cliquez ici : http://francafrique.shadow-corp.org/backup/filesender.php

Vous verrez que les echos se font sans pb, et vous ne le verrez pas mais je vous garanti que le mail n'arrive pas !

Le code non paramétré :

<?php

/*
Backup whole website and database (optional)
then send by email script

*/



// ******************************
// setup variables, edit below
// ******************************

$path = '..';// Which directory to backup? Don't add trailing slash

$backup_name = 'monbackup';// backup file name

$split_size = 2 * 1024 * 1024;//In Megabyte

//Important: Gmail doesn't allow attachments more than 10 MB.

$backupdatabase = 'yes'; //Want to backup a database also? 'yes' or 'no'
// configure your database variables below if you want to backup database:
$dbhost = 'localhost'; // Server address of your MySQL Server
$dbuser = 'xxx'; // Username to access MySQL database
$dbpass = 'xxx'; // Password to access MySQL database
$dbname = 'xxx'; // Database Name


$to = 'xxx@xxx.com';// Where to send the emails?
$from = 'backup@xxx.org';// Who should the emails be sent from?
$senddate = date("l j F Y");//Mail date format
$sendsubject = 'This is ' . $split . ' of ' . $senddate;// subject and body of message
