I am not pretending to really understand this properly But it sounds to me like this type of stuff is only for organizations. What happens to the little guy like me if this type of solution is implemented? I run my own mail server for me and my close family, I do it out of desire to understand the technology Better for my work and as a result of not being able to get the service I desire for my email needs from a Provider. I do not have a trick DNS server and would be unlikely to know how to build one. My DNS sits on a reg site with a little web front end so I can only do standard stuff on it. What I seem to see here is an assumption that the only people who should be allowed to run an email server are those doing it as a business and if you want to run a little linux box with a couple of domains with about 3 accounts each you are left out in the cold. I am aware that spam is a WAY bigger problem for you guys but it is still a real pain for me too and ultimately I may wish to send a really important email to one of your customers some day and all these clever widgets stop it getting through because I don't have the resources to set up a trick DNS etc, where does that leave me and your customer?
