Php script for mail doens't work anymore

[messa]

Hello,

I use since a few months a contact form made in Flash with a php script to send me mail, now since a couple of days (could be longer) it doesn't work anymore.
When I use this test script, that works fine
<?
mail("emailadres@myprovider.com","test","OK it works");
?>

When I use my script, it doesn't

<?
if(!empty($HTTP_POST_VARS['sender_mail']) || !empty($HTTP_POST_VARS['sender_message']) || !empty($HTTP_POST_VARS['sender_subject']) || !empty($HTTP_POST_VARS['sender_name']))
{
$to = "myemail@myprovider.com";
$subject = stripslashes($HTTP_POST_VARS['sender_subject']);
$body = stripslashes($HTTP_POST_VARS['sender_message']);
$body .= "\n\n---------------------------\n";
$body .= "Mail sent by: " . $HTTP_POST_VARS['sender_name'] . " <" . $HTTP_POST_VARS['sender_mail'] . ">\n";
$header = "From: " . $HTTP_POST_VARS['sender_name'] . " <" . $HTTP_POST_VARS['sender_mail'] . ">\n";
$header .= "Reply-To: " . $HTTP_POST_VARS['sender_name'] . " <" . $HTTP_POST_VARS['sender_mail'] . ">\n";
$header .= "X-Mailer: PHP/" . phpversion() . "\n";
$header .= "X-Priority: 1";
if(@mail($to, $subject, $body, $header))
{
echo "output=sent";
} else {
echo "output=error";
}
} else {
echo "output=error";
}
?>

Ofcourse the email adresse in my script are correct, I just taken them out...
On my local webserver it all works fine...
Can someone help me locate the source of this problem.
something changed on the webservers ?

Thanks for the help

messa

Are you on advanced php? Beginner doesn't support the mail function. Also, the big if at the beginning should probably have the ors changed to ands. But the big one i think is that $HTTP_POST_VARS needs to be changed to just $_POST. Try those.
