Cc and Bcc in mail() ...

I got a problem with receiving mails to the accounts stated in Bcc and Cc.
I use the following headers. Also, hotmail chucks the emails into the junkmail even though I have just the To: <useremail> set. Any ideas?

$headers .= "MIME-Version: 1.0rn";
$headers .= "Content-Type: text/plain; charset=iso-8859-1rn";
$headers .= "Content-Transfer-Encoding: 7bitrn";
$headers .= "From: <me@domain.com>rn";
$headers .= "To: <you@your.com>rn";
$headers .= "Reply-To: <me@domain.com>rn";
$headers .= "X-Priority: 1rn";
$headers .= "X-MSMail-Priority: Highrn";
$headers .= "X-Mailer: PHP4rn";
$headers .= "Cc: <me2@domain.com>rn";
$headers .= "Bcc: <me3@domain.com>rn";
mail("you@your.com", $subject, $message, $headers);

I would recommend reading the comments on the manual page for mail very closely...
