As I noted in a previous message, switching can be very costly for many. A provider may realize that many users have an existing vested investment in the provider's services, making any switch by the users costly. Therefore, the provider can change their policies knowing that many users will still stay with them, even if they are not happy with changes. I think all of us can think of real-world cases where such business practices have been exercised. BTW, I am not saying that such an event is inevitable. However, it is a risk to current email operations if DKIM (as it is currently defined) is widely deployed. --ewh _______________________________________________ ietf-dkim mailing list http://dkim.org
