You can change/limit which headers are used. See SENDER_HEADERS in
Defaults.py, but as has been pointed out, in most cases, you want to
look at something to determine if a post is from a list member.
If you're suggesting there should be further authentication of the
purported sender, that would be a more difficult implementation and
possibly more burdonsome than you would want for legitimate posters.
