Blacklisting email domains? (Page 1 of 2)

install some antispam registarion mods then, just stop them registring before they post. simple

Add a ban and leave the username blank, simply put the domain name under email. (Also make sure you got allow banned emails set to no in options/permissions).

You are entering the parent domain in the banned e-mail list? Do you have another PunBB running, using the same db?

I have a single PunBB running. I enter "domain.tld" to block "user@domain.tld", which I assume is the correct syntax.

Quaker: That's a good idea!

Here's a multi-rbl variation of that code Quaker posted.

//---------------Start of RBL lookup---------------//

$rblserver = array();
$rblserver[] = 'sbl-xbl.spamhaus.org';
$rblserver[] = 'combined.rbl.msrbl.net';

$fip = get_remote_address();
$rip = implode('.', array_reverse(explode('.', $fip)));


foreach ($rblserver as $xrbl)
{
        $rblcheck = $rip.'.'.$xrbl;

        if ($rblcheck != gethostbyname($rblcheck))
        {
                message("$fip blocked. Your I.P address is listed in the $xrbl database.");
        }
}

//----------------End of RBL lookup----------------//

Only lightly tested. You can add more RBL's if required, (though not necessarily a good idea), by adding more:

$rblserver[] = '[another-rbl-server]';

lines below those two already there. Those two should suit for general use, however.

mattf, what does this do? are you modifying the register.php or some sorta blockage script for those listed.

hummm that might be a good mod. a blocking script via ip address and a redirect to some stupid site.

if ip is listed then redirects.

Q

Yup. That's correct.

freakin sweet... a war on spam....hahaha...

Q

If their account isn't activated, they cannot login, hence they're a guest? Wouldn't just disabling guest viewing achieve the same?

List the IP on what criterion? If you're going down a full access block route, you should be doing this at network level, not software level, i.e: firewall.

Edit: If you are going to do it at software level, I would presume including that script from header.php itself would do the trick. Header.php is a common requirement across all forum pages.

You mean then to create your own blacklist from IP's that have spammed your forum?

By far the best method, I would say, would be to run MJT's rbldnsd server and compile the list for that so that you have your own local RBL. I use that method for the MX, and it works a treat. It's been running several years here with never a single glitch. Just set up Bind/named to forward to it for your local zones RBL entry.

It's straight forward enough. All you need to do is just set it up as a caching resolver, and add an entry for your RBL. It's worthwhile having a local caching DNS server anyhow, as it will help with your DNS traffic and speed for cached lookups. All you'd need is a named.conf file consisting of roughly:

//
//
// Local rbl zone(s)
//
//

zone "spam.rbl" in     // Or whatever name you use with your rbldnsd zone(s).
{
        type forward;
        forward only;
        forwarders
        {
                [IP.address.of.rbldnsd];
        };
};

//
// root servers
//

zone "." in
{
        type hint;
        file "named.root";
};

//
//
// End of file
//
//

That's about all you need for a caching server and forwarding to your RBL server, (if I remember correctly). You could probably just use the IP of the RBL server in that above script instead of a hostname?, but you're getting a caching resolver to boot, so it's worth setting it up just for that. It also gives you the option of using the RBL for other servers/purposes, where as a flatfile lookup would be tied to the forum.
