Please excuse the late reply: I have dozens of other urgent projects. I was disappointed in this web page. This seems to be a group that certifies or provides a `stamp of approval' for other organizations, similar to a trade organization that certifies its own members. Because of the built-in conflict of interest, the potential for corruption is very high. There's not much value for consumers here. > I agree with Vernon that in general reputation is pretty hard since the > bad guys have an unlimited supply of new domains.

This might be e-mail between members of my university and members of other universities, or e-mail between banks and travel agencies and their customers at my university. So far, from our sendmail logs, I've found one university that employs DKIM signatures on their e-mail; I whitelisted them by their Authentication-Results header. I'd like to do this for other reputable senders. I suppose what we need is for the recipients of e-mail to rate the reputation of sending organizations. Representing the recipients, I'd be willing to pay for such a service. Another alternative is some independant rating organization that ensures that the sender takes responsibility for their e-mail. Of course, even a reputable company could decide to engage in an e-mail marketing campaign to gather more customers. That sort of activity should reduce their e-mail reputation. -- -Gary Mills- -Unix Support- -U of M Academic Computing and Networking- _______________________________________________ DCC mailing list [email protected] http://www.rhyolite.com/mailman/listinfo/dcc
