I'm hearing a lot of chatter about various encrypted messaging systems, and I want to adapt the first system that makes it easy for me to: * set up a server that uses my domain. * pipe incoming messages to processes, and send from my system. * retrieve and read my messages on a variety of devices. In other words, give me the basic functionality that email used to have. And we can solve the spam problem with something like Brian Warner's PETMail proposal, though cryptologically verified senders will help with that.
