news2mail does not handle postings with different senders

[Julien ÉLIE]

4. Stussy reports that news2mail does not handle postings to multiple lists which have different envelope-from senders.

It should be handled by sending multiple messages. One would have to call mailto() for each UNIQUE SENDER in saddr{}. A null entry (or no entry) in saddr{} for a given list can match any non-null entry (but should only actually be matched to one - e.g. the first). Note that the number of unique senders is not necessarily the same as the number of lists.

Currently, the "news" user is used as the envelope-from sender when multiple lists receive a posting, or when one list omits the third parameter in news2mail.cf. The news2mail program is set up as a funneled channel in newsfeeds, implying multiple matches should be handled as one -- and multiple matching funneled feeds will result in a single call to the script.

Pseudo-code suggestion from D. Stussy:

  loop = 0;
  foreach(@saddr[@good] as sa) {
      recipient_list_array=empty
      foreach(@good) {
          if (sa == saddr[good]) then
              append maddr[good] to recipient_list_array;
          if (loop == 0 and saddr[good] == NULL) then
              append ....
      }
      send_mail(....)
      loop=1
  }
