Some peoples post to the lists without being subscribed, and expect a private
reply (or at last to get a private copy). This is especially true for
netbsd-help, but I've seen it in others lists as well.
Despite being subscribed to the lists, I like getting a private copy of
messages for threads I've involved into, because I can handle it faster
(I read the folders for the NetBSD lists only about once a day), and I may not
be alone in this case.

I handle about 200 messages a day. It's clear that if I have to do something
else than hit 'r' to reply to a message I won't do it.

For the netbsd-bugs mailing list, you clearly can't do it because gnats needs
to have the sender's address for its operations.
