Using curl to login into https site not working, suspect godaddy
verification having something to do with it

I use the following general code to log into other https sites and pull
records using forms, but it doesn't seem to work for www.voip.ms. I've
created a testing account so if anyone wants to take a crack at it and
tell me what I did wrong. (Warning, the site only gives your IP address 4
tries until it bans it)
<?php
ini_set('max_execution_time', 300);
$username="meahmatt@aol.com";
$password="testaccount";
$url="https://www.voip.ms/m/login.php";
$cookie="cookie.txt";
$postdata =
"col_email".$username."&col_password=".$password."&action=login&form1=";
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT
5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6");
curl_setopt ($ch, CURLOPT_TIMEOUT, 60);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie);
curl_setopt ($ch, CURLOPT_COOKIEFILE, $cookie);
curl_setopt ($ch, CURLOPT_REFERER, $url);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt ($ch, CURLOPT_POST, 1);
$result = curl_exec ($ch);
curl_close($ch);
echo $result;
?>
I've also tried setting CURLOPT_SSL_VERIFYPEER, TRUE with no change
