Yeah, I got the feeling this only works with Yahoo Mail. That's pretty disappointing. Is it really that much harder to make it work across at least the big email providers, while still being able to remove that setting-up the private key and sharing the public key confusion that people get when using PGP? Or is it more of a political/collaboration issue (the big companies don't want to work together on this)?
