I tried searching the forum but found nothing....and I'm assuming this is a quick question.
What DNS servers will Spam Blocker Lite allow for DNSBL lookups? I usually just use Level 3's (4.2.2.2, 4.2.2.4) or Google's (8.8.8.8, 8.8.4.4) servers. I also tried throwing in OpenDNS but all say the same. I don't want to use my ISP's (AT&T) as they are consistently bad.
