Historically, debian-user, and all of the Debian mailing lists,
have had a rule that you post and reply only to the list, and that
you do not CC anybody unless they explicitly request a CC. I have
been following that rule. However ...
Recently, someone posted something to the list and CCed me.
Since I am subscribed to the list, I get a private e-mail for
each posting to the list. If a poster also CCs me, I have been used
to getting two copies: one directly (via the CC) and one indirectly
(via the list server). But on this occasion, I got only one copy.
That makes me wonder if the list server has been "smartened up"
