The matter of protecting your e-mail is a simple one - there are standards (S/MIME). What you need to look in a provider is: (1) They SHOULD NEVER have copies of your private keys (2) They should follow published standards (3) Allow S/MIME e-mails For example, if you want to use your Gmail account with military-grade security that neither NSA can read, just install Penango in your browser and send messages encrypted - this solution is also used by US military and corporations. Penango does not hold any of your private information and/or your keys - so they can not be forced by anybody to give out your secret.. simply because they do not have it!!!!
