That appears to account for the unusual header elements and for the presence
of an HTML alternative. I tried sending myself a test message from a Yahoo!
account I keep handy in case I need it.

The result appears below my signature. I don't know why those extra blank
lines were added, but it definitely happened when I copied the data into my
mail client (Outlook Express); they don't appear in a Notepad-saved copy of
the message source.
