I am still struggling with a problem I cannot find the answer to - I've
checked all the manuals and FAQs, and posted this here before but didn't get
any useful responses.  I have several lists that *almost* always change the
format of messages sent to them, from HTML to plain text.  I *do not* have
the NoHTML setting in any of the list headers; in fact, the headers are
extremely simple - I've included a sample below.  I have a test list with a
header that was *copied* from one of the lists that have the problem, and I
cannot reproduce it on the test list.  Every message I send to the test list
comes through fine - *almost* every message sent to the real lists come
through as plain text instead of HTML.  Every once in a while one comes
through in HTML perfectly.  It's driving me crazy.

We use Exchange for our SMTP server and Outlook 2000 for most, though not
all, of the clients.  I can sent the exact same message to my test list and
one of the real lists - on the test list it appears just as I sent it, on
the real list it has reverted to plain text.  The only difference is in the
number of list members - my test list has 2, the real lists range from 10 to
over 600 but I can't imagine that would have anything to do with it.  Does
anyone have any idea what is causing this and how to fix it?
