email headers

is there a rule where in the header of an email the "bcc" should be (I dont need a cc for bcc, right?)? cos I want to send to my bcc´s and only one email gets to me (the one which is not in the bcc but in the "to"). what am I doing wrong?

Here are the headers you can use :

$headers .= "From: Name<mail@server.com>n";
$headers .= "X-Sender: <mail@server.com>n";
$headers .= "X-Mailer: PHPn"; //mailer
$headers .= "X-Priority: 3n"; //1 UrgentMessage, 3 Normal
$headers .= "Return-Path: <mail@server.com>n";
//Uncomment this to send html format
//$headers .= "Content-Type: text/html; charset=iso-8859-1n";
//$headers .= "cc: birthdayarchive@php.netn"; // CC to
//$headers .= "bcc: mail@server.com"; // BCCs to, separete multiple with commas


Also, bcc does not work with Windows.....

thx
