The actual wording in the draft (section 2.1) is

   A "sender" is the person or software (usually, but not always, the
   same as the poster) responsible for the operation of the posting
   agent or, which amounts to the same thing, for passing the article to
   the injecting agent. The sender is analogous to [RFC 2822]'s sender.

So there are two places in the draft where the meaning of "sender" is
explained (and John has been quoting from both of them on various
occasions). They do not contradict each other, but neither are they
"obviously the same". I have therefore amended 6.2 to read:

   The Sender header specifies the mailbox of the entity which caused this
   article to be posted (and hence injected), if that entity is different
   from that given in the From header or if more than one address appears
   in the From header. ...

Note that the concept of a "sender", with the same meaning, is also used
in connection with the Injector-Info header.

In the case where Bob lends his terminal to Alice to post an article, John
will no doubt continue to argue that Alice is the sender, and the rest of
the list will argue that it is Bob (he being responsible for his
terminal). However, I have no plans to refine these definitions further,
unless I hear a consensus to do so.

Just to remind you where ae are now at. An injector MAY fill in an absent
Sender header (but it SHOULD NOT alter one already present), but there is
a warning that there are privacy implications, and a pointer to the
Injector-Info header.

Again, I have no plans to change this further unless I hear a consensus to
do so.
