I guess my questions really is 'do the existing per-list customisation options include any way of changes to the mail headers beyond what is already accessible from the GUI?'
And, as a followup, if it requires source code level changes, is there a sane and sensible way of doing these on a per list basis so my installation remains upgradable? I know python, but I'm in no hurry to make by installation unmaintainable.
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 simply:
# # DavidsHeader.py """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
>>>m.pipeline.insert(m.pipeline.index('CookHeaders')+1, 'DavidsHeader')
>>>m.Save()
>>>{Ctrl-D}
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.
