This is far fetched. But what about a mailing list system that
stores subscribers in a database, together with the lists they are
subscribed to. That way, when the mailer gets ready to send out mail
to each user, it could compare Message-Ids and only send one copy of
a message (maybe to a preferred list?)
Of course, this could only work on the systems that implement this
idea, and would probably take some more CPU time doing the comparisons
(unless it kept a running table of cross-posted email)
Does this make any sense? I wonder if it could work.
