To elaborate a bit. RFC 5322 says
The "From:" field specifies the author(s) of the message,
that is, the mailbox(es) of the person(s) or system(s) responsible
for the writing of the message. The "Sender:" field specifies the
mailbox of the agent responsible for the actual transmission of the
message. For example, if a secretary were to send a message for
another person, the mailbox of the secretary would appear in the
"Sender:" field and the mailbox of the actual author would appear in
the "From:" field.
In that sense, many of us think that the person who wrote the post is
still the author even if the list made a few simple changes that didn't
alter the basic text of the original message while the list is a Sender:
That's why we believe that Munge From is non-compliant. You may think
that the list is in fact "the person(s) or system(s) responsible for the
writing of the message", but many people don't agree.
