Yes, it's because Eudora uses Internet_Explorer_Server component to
display the content of the email. And the previously mentioned DoS case
with the nested <marquee> tags concerns the Internet Explorer as well.
If you want to trigger this DoS under the IExplorer you have to include
<style></style> tags in the two separate lines and you have to refresh
the page, only second page fetch freezes the browser.
