It's also why I created the ``provider delegations'' in the MVP proposal.
But the argument that Alan seems to be using in this thread is that mobile
users want to be able to send from anywhere AND protect their domain name
from forgery at the same time. None of the RMX/DMP/SPF/Vixie/DRIP/MVP
proposals achieve that. That WILL require cryptographically signed messages
to achieve, and I think that's where email is going in the long term due
to the forgery issues.
