Greg, Usually we use forwarders so we don't always have to bother root servers. Because our ISP's deals with great amount of requests from all the clients, probably most of your new requests are already in their cache and it's much faster than query a root server, because it's on the same network. I mentioned the forwarders parameter because it's usual to use our ISP's dns servers as a forwarder and I thought you might had a misconfigured forwarder. Although you have forwarders configured, from the point of view of your dns clients your dns server still answers the requests the same way, and if you have a problem with your dns server, the problem still remains, so, you are not putting the problem away.

All the requests to spamhaus.org will be made by your postfix box, not from your forwarders. And look, your server only queries forwarders when its own cache expired, before that your server answers the queries by himself, without bothering forwarders. I use spamhaus.org with postfix/spamassassin and I've got no problem with it.
