thank you for that clarification. I noticed that other mails,  
seemingly of the same nature, have no declaration of "alternative  
parts", but rather are simply declared as "mixed" or have no text part  
at all, leading to the button to display the HTML version.

Do you think it'd be a useful enhancement to treat "empty"  
(white-space only) parts as not existent, so that in the semantically  
malformed, but still typical case of "alternative" with non-empty  
HTML, but empty text-only part, the user receives an indication of the  
HTML part even if (s)he chose to only display text parts by default?

Regards,
Jens
