problem receiving emails in hotmail.com addresses

[Hop_Hop]

Hotmail.com does not receive emails when i send them with mail() function from PHP ... What is wrong ??

My script is :

$to = "slbzlatv@hotmail.com";
$subject = "You've got mail!";
$message = "Hello someone.";
$headers = "From: admin@domain.net\n"; // I suggest you try using only \n
$headers .= "MIME-Version: 1.0\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\n";
$headers .= "Return-path: me <admin@domain.net>\n";
$headers .= "X-Priority: 1\n";
$headers .= "X-MSmail-Priority: High\n";
$headers .= "X-mailer: PHP";

mail ($to, $subject, $message, $headers, "-f admin@domain.net");

Qmail-send tells me this :

@4000000044b6ceb7340da53c new msg 427543
@4000000044b6ceb7340f2fc4 info msg 427543: bytes 420 from <admin@hopzone.net> qp 8885 uid 33
