You're welcome.  This kind of problem gets sadly technical really
quickly.

I really should keep my random opinions to myself.  I'm sure it does a
good job, I was just annoyed that it made tracing the message harder.

Perhaps when sending a message Outlook parses those headers in the
text to get the information it gives to the MTA as envelope addresses.
What does the CC in the "Sent" message (any view you can get of it!) 
have related to "Judy", if anything?

Not terribly important, since we don't think the Exchange boxes are
doing anything except passing on a bare "Judy" in the CC field.  But
without copies of the queuefiles we can't tell where it was introduced.
