That is quite true, but in this example, the mailing list is the
'sender' of the message I receive. It is not the 'author' of the
message. You are still the 'author'. RFC 5322, sec 3.6.2 and
predecessors are clear:

   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.
