It can. Mailman has already been changed to take ownership of the
"From:" line pointing it to some list-owned address and injecting a
reply-to optionally to allow unicast msgs to work too.
The problem is that mailing lists forging From addresses looks the same
to software as a spammer forging the same. No progress is going to be
made till mailing lists stop doing that.
