Remember, remember, remember: A message can be addressed to many
recipients, some of which are BCC recipients that appear only in the
envelope and should not be revealed to other recipients.
The Received: header is built when a message is received, and is the
same for all copies of the message that are sent to all recipients.
The $original_local_part and $original_domain variables are set only
during *one* delivery, to refer to the envelope recipient that refers to
that one delivery. Therefore, they cannot be used in Received.
You could craft some special header using a transport filter, I suppose,
but why bother? Exim already provides the option to add an
Envelope-Sender: header to messages as they are delivered. For example,
messages sent to postmaster on my system get to me, but they contain the
line
Envelope-to: postmaster@xxxxxx

The spec does go on about processing addresses in its description of the
$original_xxx variables. I'll try to make that more explicit.

You can set log_received_recipients to cause the list of envelope
addressees to get put into the log.

In a filter file, people often want to check the local part, which is
why I provided them split up.
