Automated read notification?

Hi, if in an email there's this sequence of headers:
X-CP-RMS-Expiry: 2007-06-06T16:02:28.790Z
X-CP-RMS-Type: Normal
X-CP-RMS-Size: 2257053
X-CP-RMS-Attachments: 5
X-CP-RMS-Site: tin.it
X-CP-RMS-Display: Pickup
X-CP-PS-Service: RMS
X-CP-RMS-C-Element: iyq0Or8S0F7VGNlLfnniBAMGyKff7nYc50651
X-CP-RMS-V-Element: _unreg_47yobecf
X-CP-RMS-QUERY-Element:
http://communicator.maximail.alice.it/r.jsp?d=tin.it&wr=_unr eg_47yobecf&ws=1o2e6hbr&e=tin.it&c=iyq0Or8S0F7VGNlLfnniBAMGy Kff7nYc50651

Can it be an automated system for telling if the email has been read?
Expecially the last header, X-CP-RMS-QUERY-Element: http://sitename.

Headers in emails when are processed? Is the email client (outlook express)
which processes them or the mail server?
In this case, the X-CP-RMS-QUERY-Element: when is processed? By the client
on the local machine or on the remote server?

Thanks.

It can be anything the sender wishes it to be, including nuclear launch=20
codes.

Both the mail server, and the mail client, are free to process any header=20
they know how, or wish to, process.

ent=20

Yes.

If whatever mail server handles this message is specifically programmed t=
o=20
launch nuclear missiles, when it sees this header, then this is what it w=
ill=20
do. If whatever mail client handles this message is specifically programm=
ed=20
to reformat your hard drive, when it sees this header, then this is what =
it=20
will do.

The question you /should/ be asking is whether the specific mail server y=
ou=20
use, or Outlook Express, does anything with these specific headers. As fa=
r=20
as Outlook Express goes, the only one who can give you an authoritative=20
answer is Microsoft. These are not any kind of standard headers. There is =
no=20
Internet standard whatsoever -- thankfully -- for mandatory read receipt=20
notifications.

That, of course, does not mean that some mail server, or some mail client=
,=20
wouldn't have some kind of a dubious read-receipt notification mechanism,=20
that gets triggered by a special header.
