I cam home today and found three alerts telling me that the firewall had protected me by blocking access to 18.104.22.168 on port 80. This IP address is for lookup.mailfrontier.net. I tried to figure out what program might have done this and it appears to be the ZA spam filter in Outlook. Why would the spam filter try to access a web site directly and not via email? And if it was the ZA spam filter, why wouldn't it have been autocofigured to not block it?
