Question: how does mail2news address the case that a "cross-posting"
shows up on two of the mailing lists that it converts? Reusing the
Message-ID is a problem for such cases. I once read a document on the
conditions that allow to transform the Message-ID, References,
In-Reply-To:, ... in a reproducible and reversible way in this case
(presumably by adding the group name and the host name); I don't quite
recall what it was, it may have been written by Bettina Fink; in any
case, the discussion had taken place on
news:de.comm.software.newsserver.
