Looking for the opposite of "banned emails"

[Idodo]

i need to allow users to register only with email providers that i choose (like ISPs).
there is too many free emails service and i can't ban them all.
so i need to allow users to register only from domains that i want.

Thanks,
Ido.

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 )

[Idodo]

I'll check it right now
thanks!

Floris have this for his site. He blocks yahoo and aol lol.

Any chance of expanding this request, so it would work like the following,

when someone tries to register though a email in the allowed list he/she has no problems, how ever if a unknown domain is used, the admin has the verify the user, if the admin verifies the user the domain is added to the accept list automatically or manually.

thanks

can someone get this working for 3.5.4?

[JMikeS]

This doesn't work with 3.6, any suggestions? The original function is:

PHP Code:

// ###################### Start checkbannedemail #######################
function is_banned_email($email)
{
    global $vbulletin;

    if ($vbulletin->options['enablebanning'] AND $vbulletin->banemail !== null)
    {
        $bannedemails = preg_split('/\s+/', $vbulletin->banemail, -1, PREG_SPLIT_NO_EMPTY);

        foreach ($bannedemails AS $bannedemail)
        {
            if (is_valid_email($bannedemail))
            {
                $regex = '^' . preg_quote($bannedemail, '#') . '$';
            }
            else
            {
                $regex = preg_quote($bannedemail, '#') . ($vbulletin->options['aggressiveemailban'] ? '' : '$');
            }

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

    return 0;
}
