I signed up for countermail in March. Pretty happy with it, except on a mobile phone I have to run it through the K9 mail app for it to work. Takes a day or so to set it up and a little studying, but that is better than having someone intercept your private emails. I believe the reason it is a little complex to set up is because of all the encrypting and decrypting. It sends the email to your phone fully encrypted, and you have to enter a password to make it decrypt every time you log in. Even if someone got your phone and checked it, all they would get is a bunch of gobbly gook, unless you gave them the decryption password. Nothing is 100 percent, just try to make yourself a hard target.
