Re: Processed-By (or Transmitted-By) header concept

William,

The problem I see with this is that multiple hops cannot be used in
conjunction with New-xx and Original-xx headers.
What you'd have to do would be to use a single header which both identifies
the hop that changed the headers and records the change.

Lets assume that the regular headers are rewritten and therefore contain
the "new" values, so we only really need to preserve the history.
That can be accomodated in the "Processed by" by simply inserting the
original values for the fields logged as changed.

Processed-By: odin.ietf.org (ip=[132.151.1.176])
  on-behalf-of ietf(_at_)megatron(_dot_)ietf(_dot_)org
  changed-fields List-ID=oldvaluee,Sender=oldvalue,CC=oldvalue,

Envelope-Recepient=oldvalue,Envelope-ReturnPath=oldvalue,Envelope-Submitter=oldvalue

  process-type maillist (list-id=<ietf.ietf.org>) ;

As for the name, call it like it is. If this is to address the issues of
automatic (c.f. by a users explicit action) re-insertion of messages into
the delivery system call it
"Reinserted-by"


But... also add a timestamp so we can accurately order these things

Reinserted-By: odin.ietf.org (ip=[132.151.1.176])
  on-behalf-of ietf(_at_)megatron(_dot_)ietf(_dot_)org
  changed-fields List-ID=oldvaluee,Sender=oldvalue,CC=oldvalue,

Envelope-Recepient=oldvalue,Envelope-ReturnPath=oldvalue,Envelope-Submitter=oldvalue

  process-type maillist (list-id=<ietf.ietf.org>) ; Tue, 28 Sep 2004
00:43:21 -0700 (PDT)

At the end of the day though it still looks like a mechanism by which
someone could fabricate a whole imagined history for a message, rather than
anything upon which we could rely.

Together with it introduced are
Original-???? headers which are to be used to preserve original
values of the headers that are being changed.
