No sane (ie RFC compliant) mailing list uses an envelope sender of the
original sender - if they did the original sender would get all the
bounces and so the MLM would be unable to do things like bounce
management - and the list members would quickly get pissed off at the
weird bounces they received.
Some MLMs modify the From: header, some do not (or they may change the
header depending on the role they are playing). To a large degree it
depends on the type of list - on this list messages are definitely
associated with the author, on an announce type list it might be
preferable to make the list itself be the origin of messages.
