I have a Samsung Galaxy Stardust with Android 4.3. In the email app, under security options, there is an option that says "encrypt all outgoing email". But my understanding of S/MIME is that in order to encrypt e-mail to someone, I have to have their public key. So it seems like this option can't really do what it says it does.

  • It likely means to use SMTPS, not S/MIME or S/GPG. – Lie Ryan Aug 16 '15 at 2:14
  • @LieRyan, when you set up a mail account, there are settings for communicating with the mail server with SSL, so if "encrypt all outgoing email" meant the same thing, that would be redundant. – JWWalker Aug 16 '15 at 14:35

It actually gets the public key of the receiver before sending the email. So yes, it could do what it says.

  • Gets the public key how? Unless that person has already sent me a signed message, I don't see how it would be able to get the public key. – JWWalker Aug 16 '15 at 14:32
