My PHP skills aren't so hot, and this script that USED TO work, but has not ever been changed, no longer works now.

This is for Live Feedback Registration and vB 3.8.3. It's the email verification function. It always ends up failing to connect to legitimate email address'.

If anyone could just look over the code real quick and see if anything stands out I'd really appreciate it. I'd like to get this working.

Everything else but the email check works just fine.

email_check.php

PHP Code:


			
<?php

require_once './global.php';
$vbulletin->input->clean_array_gpc('p', array('email' => TYPE_STR));
if($vbulletin->GPC['email'] != '')
{
    $email = htmlspecialchars_uni(trim(convert_urlencoded_unicode($vbulletin->GPC['email'])));
    $verify = (!ini_get('safe_mode')) ? verifyMailAddy($email) : 0;
    header('Content-Type: text/plain;');
