Cyber, Hush, Elite are all true PGP-encrypted e-mail services. With ziplip, when you send an encrypted message, only a reciever that has ziplip can read it. Also, it doesn't store messages on their server as "encrypted." There are getting to be more and more people (board members AND sources) that won't correspond unless you have a true PGP-encrypted e-mail service.
Operamail must have a different version of PGP?!?!
Does the info that's stored on their server (messages) get encrypted?
I know when I try to send an encrypted message to an Operamail account I get an encryption key error. I think keptprivate is another one like Operamail.
