Solution, part 1: The author's MUA, knowing that the author is on the
list, adds Mail-Followup-To showing the list name.
Solution, part 2: Your MUA automatically sends followups to
Mail-Followup-To instead of From+To+Cc.
This is a simple matter of programming. It's already supported by mutt,
for example. Ask your favorite MUA authors about Mail-Followup-To!
In the meantime, I've also set up some active short-term protection for
my own mailbox:
|bouncesaying 'See pobox.com/~djb/docs/copies.html.' iftocc in `cat .lists`
But that merely shifts the suffering. Mail-Followup-To eliminates it.
