You can change the templates, but I don't recall off the top of
my head whether that allows you to change the headers used within the
message. I don't think it does, but I might be wrong.
To change the templates, you'll need to have command-line access
to the server. Modifying these is not possible from the web admin

On a per-list basis? No. If you wanted to make modifications to
the headers, you'd either have to make a single change in a central
place that is reflected in all the headers on all the lists, or you'd
have to invent your own infrastructure to support a per-list
mechanism for changing/adding headers.

Procmail would be one potential solution, but I don't recall of
having heard anyone say that they'd done this sort of thing before.
Of course, now that I've said this, I'm hoping that someone else will
pipe up and tell me that I'm wrong.

Then the FAQ entry must have left you with an incorrect
impression, because through modifying the templates, you can make
changes to the message bodies, and that can be done on a per-list
basis. Moreover, those message bodies are capable of using variable
substitution field names on a per-user basis. This is how we create
the footers on some mailing lists that will have a link direct to
your user login page for the list in question.
But there are limits to what you can do. That is the key
impression that I had hoped to leave with the FAQ entries on this
