This is correct for the headers, but I think in order to anonymize
the list _posts_ you need to do some more postprocessing. For example,
when a user quotes another user, the introduction line, followed by
the quote, might contain the quoted user's address:

If you need _that_ feature too, you'd have to postprocess the messages
or strictly enforce the omission of e-mail addresses in the posts. I'm
not sure if GNU Mailman has a built-in function or a pluggable module
for that purpose...
