This is actually pretty trivial to do. You can even get by without
learning Python (well, you'll need to know just a smidgen - but there
are plenty of examples in Mailman's code). 

<This is also discussed quite thoroughly in the archives!>

from ~mailman/Mailman do a grep looking for one of the current headers:
  grep X-List */*

This will show you every file that handles the X-List headers. You
probably just want to edit ~mailman/Mailman/Handlers/CookHeaders.py and
add your own.  You might want to put in a check that only adds the
header to a specific list.

Remember to make a backup copy of any files before you edit them! Good
Luck.
