Can you describe this additional header in more detail?  Better yet
would be some documentation on the web describing this header.  I.e. if
it's a standard (or maybe even a proposed standard), perhaps Mailman
should support it out of the box.

It's actually pretty easy to add such a header.  One option is to just
include the header in the original message.  Or you can get Mailman to
add it to every message by modifying the code in the pipeline.  The
place to start would be Mailman/Handlers/CookHeaders.py.  That's where
the RFC 2369 headers are added for example.
