In this paragraph a term "originator of the message" is used for the first
and the only time, and is nowhere defined. Other text only speaks of
"originator fields" (= From, Sender, Reply-To).

Also, the term "transmitter" is used here for the first time too,
and is never defined.



The proper term could be borrowed from the:

> The "Sender:" field specifies the mailbox of the agent responsible
> for the actual transmission of the message.

so
  'originator of the message'
should actually be:
  'mailbox of the agent responsible for the actual
   transmission of the message'
  (although this is unsightly long and repeating the just said)
or just:
  'transmitter' (if it were defined elsewhere)

Looks like a term needs to be invented for the agent specified in
a Sender field, or the text rephrased to avoid the need for a
new term.
