Have you reported this to Dell?  This sounds like something that anyone
at Dell who understands the technical issues would want to fix.  If
you've reported it publicly, i'd appreciate a pointer to the discussion.

If you'd care to forward me a zipfile containing examples of at least
two distinct messages with the same message ID, i'd love to look through
a copy of this sort of confusion.  It's good to understand the different
ways these sort of things go wrong.
