I notice that some of you are using digital signatures now, and I want to do that also. Is there a good getting-started document on this, especially with respect to digitally signing emails in Evolution? When I see a digitally signed mail from, say, Michael Schwendt, I'm invited to click on the "lock" icon which appears below the text of his mail. The lock opens and I get several lines of text to he effect that the authenticity of the email could not be verified because the public key isn't available. Since Michael is not including his public key in the email -- at least, Evolution shows me nothing -- I assume he (and several others) are using key servers. How can I point Evolution to the right key servers? Bob Cochran Greenbelt, Maryland, USA
