How to Get Full Headers From Juno

On the drop down menu Options, choose Email Options (press ctrl-E). Under Show Message Headers, select the full option. Click the OK button to save the setting.

Juno version 4+ can display MIME and HTML email, but does not provide a way of Viewing the HTML Source for the message within Juno.

To get the full source, including HTML codes:
In the Juno mail client, click "file" and then "Save Message as Text File.." (ctrl-T).
Give the file a name which you will remember (many people save temporary files to the desktop).
Double-click on the resulting file.
