One very important point, and a very unfortunate one, is that many, many people are going to assume from the name that Tor Mail actually had something to do with Tor. Tor Mail was a completely independent project that was thrown together by a completely separate group of people. I remember many of the Tor developers at the time who pointed out how confusing this would be for users, and asking Tor Mail to change their name. Tor Mail refused. This is like a bunch of people just getting together and releasing a product called Google Pop-Tarts and people blaming Google when it call comes crashing down. Different people, different project, "borrowed" name.
