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=_unreg_47yobecf&ws=1o2e6hbr&e=tin.it&c=iyq0Or8S0F7VGNlLfnniBAMGyKff7nYc50651

Can it be an automated system for telling if the email has been read?

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

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?

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

In this case, the X-CP-RMS-QUERY-Element: when is processed? By the client on the local machine or on the remote server?

Yes.

If whatever mail server handles this message is specifically programmed to launch nuclear missiles, when it sees this header, then this is what it will do. If whatever mail client handles this message is specifically programmed to reformat your hard drive, when it sees this header, then this is what it will do.

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

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