PEAR, Mail Queue and Mail Mime

[P@]

Hello,

I have some trouble with my application.
It is written with PEAR, SMARTY ....
I should send an email to me and with Bcc to 50's else adresses.
But it send it just to me.
I am on an easyPhP server.
Here is my code

$mail_queue =& new Mail_Queue($db_ options, $mail_options);

$from = 'my@email.org';
$from_name = "MY";
$replyTo = "my@email.o rg";
$message = stripslashes($m sg);
$from_params = empty($from_nam e) ? '"'.$from_name. '" <'.$from.'>' :
'<'.$from.'>';
$hdrs = array( 'From' =$from_params,
'Reply-To'=$replyTo,
'To' =$from,
'Bcc' =$liste,
'Subject' =$sujet );

$mime =& new Mail_mime();
$mime->setTXTBody($ms g);
$mime->addAttachment( $pdf, $attach_type);
$body = $mime->get();
$hdrs = $mime->headers($hdrs) ;
$seconds_to_sen d = 1;
$delete_after_s end = true;
$id_user = 7;
$mail_queue->put('','My Organisation',$ from, 'my@email.org', $hdrs,
$body, $seconds_to_sen d, $delete_after_s end, $id_user);


$liste follow this pattern "titi@tito.fr<t iti@tito.fr>,
tita@tito.fr<ti ta@tito.fr>,tit z@...titz@ tito.fr>,
tite@tito.fr<ti te@tito.fr>,"

How can I do to send My emails to the Bcc's addresses too ???

Does someone know something about this ???
Thanks for your help
P@
