ciao a tutti,

sto tribolando da un pò con la funzione che dovrebbe verificare l'IPN di ritorno dai pagamenti paypall,

i pagamenti funzionano solo che con questo script non ricevo mai nessuna email :

codice:
 error_reporting(E_ALL ^ E_NOTICE);
$email = 'lamiaemail@mail.it';
$header = "";
$emailtext = "";
// Read the post from PayPal and add 'cmd'
$req = 'cmd=_notify-validate';
if(function_exists('get_magic_quotes_gpc'))
{
	$get_magic_quotes_exits = true;
}
foreach ($_POST as $key => $value)
// Handle escape characters, which depends on setting of magic quotes
{
	if($get_magic_quotes_exists == true && get_magic_quotes_gpc() == 1){
		$value = urlencode(stripslashes($value));
	} else {
		$value = urlencode($value);
	}
	$req .= "&$key=$value";
}
// Post back to PayPal to validate
$header .= "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
$fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);


// Process validation from PayPal
// TODO: This sample does not test the HTTP response code. All
// HTTP response codes must be handles or you should use an HTTP
// library, such as cUrl

if (!$fp) { // HTTP ERROR
} else {
// NO HTTP ERROR
fputs ($fp, $header . $req);
while (!feof($fp)) {
	$res = fgets ($fp, 1024);
	if (strcmp ($res, "VERIFIED") == 0) {
		// TODO:
		// Check the payment_status is Completed
		// Check that txn_id has not been previously processed
		// Check that receiver_email is your Primary PayPal email
		// Check that payment_amount/payment_currency are correct
		// Process payment
		// If 'VERIFIED', send an email of IPN variables and values to the
		// specified email address
		foreach ($_POST as $key => $value){
		$emailtext .= $key . " = " .$value ."\n\n";
		}
		mail($email, "Live-VERIFIED IPN", $emailtext . "\n\n" . $req);
	} else if (strcmp ($res, "INVALID") == 0) {
		// If 'INVALID', send an email. TODO: Log for manual investigation.
		foreach ($_POST as $key => $value){
		$emailtext .= $key . " = " .$value ."\n\n";
		}
		mail($email, "Live-INVALID IPN", $emailtext . "\n\n" . $req);
	}
}
fclose ($fp);
sto diventando matto perchè le email non arrivano mai , lo script è esattamente quello che fornisce paypall per i pagamenti.

qualcuno sa aiutarmi?
