If you are not willing to take these risk, you can disable IE rendering and use Eudora's own crude but secure HTML viewer instead.
Turn Off Internet Explorer HTML Viewing in Eudora
To disable Internet Explorer HTML email viewing in Eudora:
- select Tools | Options from the Eudora menu.
- Go to the Viewing Mail category.
- Make sure Use Microsoft's viewer is not checked.
- Click OK.
Open Individual Emails in Your Browser
