You should open a Bugzilla ticket on this, and ATTACH, NOT COPY/PASTE the ENTIRE original message as an attachment to the bug ticket. That way someone will be able to look at it and see what is really happening.
Since you pasted that into the text, I have no clue on what any transport agents or mail readers may have done with the text. (Which is why you need to attach the message to the bug report, not paste it.) If they haven't mangled it too badly, what I see is a lot of missing required blank lines following the header and all of the content headers. The headers end with a blank line. Loren
