There are relative levels of security. The tools need to allow full
automation of the process, or else it won't happen. Users could be offered
varying levels of automation and security and allowed to make a choice. It
could be a simple as three buttons labeled like this:

 - Protect all my outgoing email if possible (Default)

 - Don't bother protecting my email

 - Advanced

You are confusing authentication with encryption.

Authentication is complex, but encryption is relatively simple. If I want
to send you an encrypted message, I don't need to worry about whether your
electronic identity <peter.schuller@infidyne.com> is connected to the real
world person "Peter Schuller". I just need to get a key that can be used
by <peter.schuller@infidyne.com> to decrypt the message. Compared to
authenticating a connection between an identity and a person, getting that
key is easy.
