title: javamail combine html and plain text
body: <p>I've seen many answerns in StackOverflow of how to send a mail with both, plain text and html text. My question is, how can I show some kind of link in the html part to see the text part? (something <code>click here to see plain text</code> and show the plain text version when clicked)</p>
  
  <p>Thanks.</p>
