There is a LOT of html missing in the code segments you included. Did you by any chance clip off some of the html code in the message? Perhaps between "Content-transfer-Encoding:quoted-printable" and "<font face="? In a properly formatted html page I would expect to see
Code:
<html>

<head>

…and that is just the beginning of the missing html code I would expect to see in a correctly formed page. Since this is coming from two reputable sources I can only speculate that something is happening during the MIME decoding. I have seen this in some elderly versions of OS X and Mail but not in anything as recent as Lion.
  • Are you using Mail or some other email client?
  • Have you tried looking at the messages using the online web mail portal?

If we knew what it was we were doing, it wouldn't be called research, would it?
