if (!$fp)
echo "www.google.com - $errstr ($errno)n";
else
echo "www.google.com - okn";
$fp = fsockopen("smtp.gmail.com", 465, $errno, $errstr, 10); // NOT work
if (!$fp)
echo "smtp.gmail.com 465 - $errstr ($errno)n";
else
echo "smtp.gmail.com 465 - okn";
$fp = fsockopen("smtp.gmail.com", 587, $errno, $errstr, 10); // NOT work
