Hi all - Has anyone got any rules for stopping MSGTAG.com from sending unauthorized read receipts - I have been looking all over the place since I received a message with one earlier today. Basically it embeds a picture in the message that confirms being read by virtue of being accessed. I tried blocking the parent IP in my perimeter firewall but the image still renders, and the website will as well. obviously blocking all html in messages would be effective, but there's enough useful material coming in in that form that makes the cure worse than the disease -- something I'm sure the makers of this product count on. It's basically the same trick that spyware uses to confirm email addresses. I find it to be a terrible invasion of my privacy , among other things. I checked thier website and there's no information readily available about blocking this there. I ran across a few references elsewhere that mention 3rd party products that will prevent this but no configuration information. I only received one message so I don't have any log traffic to analyze but it creeped me out enough that I don't really want any additional log traffic to analyze anyway. TIA -- Ken _______________________________________________ firewall-wizards mailing list firewall-wizards () listserv icsalabs com https://listserv.icsalabs.com/mailman/listinfo/firewall-wizards
