email security

Hi anyone have any information on email security? I was just talking with a website host who doesn't offer a secure login to the webmail client (horde). He seemed to say that securing email isn't common. My own host does allow this.

When I send an email through a https connection is the email encrypted? Or only from my computer to my server? Are emails simply insecure?

How insecure is insecure and how likely is it that someone will hack it?

Thanks a lot,

Misha
