PayPal IPN Invalid [Completed]

[marince]

ho installato su OsCommerce vers. v2.2 RC2a il modulo osCommerce PayPal IPN v2.3.4.7.
I clienti pagano tranquillamente poi mi risulta sullo stato dell'ordine PayPal IPN Invalid [Completed] e mi arriva un email con le variabili POST e GET qui di seguito:

$_GET:

language=italian

con la scritta xxxxxxxxxxxxxxxxx ho cancellato i dati.

Sapete quale sia il problema nel file ext/modules/payment/paypal_ipn/ipn.php e perchè la variabile $result sia diversa da 'VERIFIED'?
Grazie

dimenticavo queste informazioni:

cURL support enabled
cURL Information libcurl/7.19.0 OpenSSL/0.9.8g zlib/1.2.3

grazie

Il problema che mi ritorna con $result == 'INVALID' invece che $result == 'VERIFIED'.
