is there a way to send encrypted email? so that if the person on the revieving end of the email doesnt have the key they cant view the email?
This question has to go on my "oh, for Pete's sake" list, because if you haven't noticed how many people on this very list sign (a lesser form of encryption/authentication) their mails, it can only be because you don't have any mail encryption software installed yourself. If you did, you wouldn't have to ask this question ;-) .
In any case, what you need is GNUPG (gpg); most, if not all email clients I am familiar with have some facility to encrypt and decrypt mails using it as a backend.
If you use Thunderbird, you'd have to install the Enigmime/Enigmail extension to encrypt/decrypt mail; iIrc, other clients such as Mutt or sylpheed-claws I believe need nothing extra as long as GPG is installed, probably you'd have to make sure you used the proper USE flags when installing Evolution, but Evo may have the facility natively (if it finds GPG is installed).
