Blacklist comments from open and insecure proxies not working any more

Hi,

I found out that “Blacklist comments from open and insecure proxies.” would do a RBL test at opm.blitzed.org (at least in WP 2.0.3).
However, this RBL has ceased to exist: http://lists.blitzed.org/pipermail/opm-announce/2006q2.txt

I suggest changing it to (for instance) sbl-xbl.spamhaus.org

For those who want to do that themselves (on 2.0.3):
– edit wp-includes/functions-post.php
– find this line:
$lookup = $rev_ip . ‘.opm.blitzed.org.’;
– change to this:
$lookup = $rev_ip . ‘.sbl-xbl.spamhaus.org.’;
– save and exit
