"The Evolution preferences menu is divided up into two parts. In
the left-hand side vertical column menu is what I call the General
Preferences. These apply to the application itself. When you create
an email account, then you click on it and click on Edit to edit
the preferences for that account. I call these the Account
Preferences and they open up in a separate window.
"Create your email account and then go into the Account
Preferences. Select Security at the top. Then type in the Key ID.
Have a look at the four options and click OK when you're done.
"Now, to send someone an encrypted email you need to have their
Public Key in your "Key Chain".
"You can get their Public Key if they can send it to you as an
attachment (which is why I advocated saving your Public Key as an
separate attachment in Part I, so you can easily send it to
others!) or you can download it from a Public Key server (but only
if they have uploaded it)."
