quick'n'dirty but should work:

open includes/functions_user.php find this function:

PHP Code:

// ###################### Start checkbannedemail #######################
function is_banned_email($email)
{
    global $vboptions, $datastore;

    if ($vboptions['enablebanning'] AND !empty($datastore['banemail']))
    {
        $bannedemails = preg_split('/\s+/', $datastore['banemail'], -1, PREG_SPLIT_NO_EMPTY);

        foreach ($bannedemails AS $bannedemail)
        {
            if (is_valid_email($bannedemail))
            {
                $regex = '^' . preg_quote($bannedemail, '#') . '$';
            }
            else
            {
                $regex = preg_quote($bannedemail, '#');
            }

            if (preg_match("#$regex#i", $email))
            {
                return 1;
            }
        }
    }

    return 0;
} 


and change it into:

PHP Code:

// ###################### Start checkbannedemail #######################
function is_banned_email($email)
{
    global $vboptions, $datastore;

    if ($vboptions['enablebanning'] AND !empty($datastore['banemail']))
    {
        $bannedemails = preg_split('/\s+/', $datastore['banemail'], -1, PREG_SPLIT_NO_EMPTY);

        foreach ($bannedemails AS $bannedemail)
        {
            if (is_valid_email($bannedemail))
            {
                $regex = '^' . preg_quote($bannedemail, '#') . '$';
            }
            else
            {
                $regex = preg_quote($bannedemail, '#');
            }

            if (preg_match("#$regex#i", $email))
            {
                return 0;
            }
        }
        return 1;
    }

    return 0;
} 


that inverts the banned email checking of vb, so all emails you enter in the banning textfield will be allowed, and every mail else won't be.

(at least it should )
