I think the best way to do this sort of thing is add a handler to that
list's pipeline that does the processing you want. If you created a
DavidsHeader.py in your Mailman/Handlers directory that contained
"""Add a list specific header
def process(mlist, msg, msgdata):
msg['X-Davids-Header'] = 'my header text'
And then add that handler to the pipeline for the list in question (say
after the CookHeaders handler) using withlist:
$ bin/withlist -l mylist
Your list will be processed with the additional handler that does
nothing but add a header.
Alternatively you could also use the extend.py mechanism to add the
header on a list-specific basis.
