There is no way to do that.  The email I'm now sending will be sent to
two different places, and the list server can not assume that you had
one delivered already.  The only thing you can do is on your side, for
example, use procmail with something like:

  # === duplicates ===
  :0 Whc: msgid.lock
  | formail -D 8192 msgid.cache
  :0 a
  {
    :0 fhw
    | formail -I "Subject: *** DUPLICATE *** $SUBJECT"
    :0:
    $DEFAULT
  }

It is mailman.  It might sound tempting to hack a mailing list in
Scheme, or some other mail-related stuff, but there is a simple
solution -- try it.  After doing that, my conclusion is that I want to
be as far as possible from these things.
