I get a hint of the reason by saving the messages using "mutt".  Those of
which I get a single copy are saved under =9fans, the others are saved under
=<sender> where <sender> is the login ID of the originator.

Mutt and Elm are very similar in this respect.  Since the Reply-to: heading
(against NET convention, but it's probably OK) is munged to the list, and
the only other possibility is the format of the "From" header.  Mine is
Lucio De Re <lucio@proxima.alt.za> versus the option, say,
lucio@proxima.alt.za (Lucio De Re) which MUTT won't let me try :-)

Or perhaps a "sender" address?

Something triggers a different response in the mailing list or news to
gateway software.  Of course, the source itself may be an explanation.
