Hi All,

I have a question pertaining to message headers on outbound mail from
remote smtp auth'd clients.  I have been asked to adjust our mail systems to
"anonymize" said remote clients.  Using mail sent from an Iphone as an example,
the headers on the receiving end show:

Received: from [10.176.149.227] (unknown [32.136.180.43])
      (using TLSv1 with cipher AES128-SHA (128/128 bits))
      (No client certificate requested)
      by smtp.ourcompany.com (Postfix) with ESMTPSA id 593E0BA56
      for <[EMAIL PROTECTED]>; Sat, 29 Nov 2008 15:20:06 -0500 (EST)


The desired outcome is to have the above adjusted to something similar
to:

Received: from remote-client.ourcompany.com
(remote-client.ourcompany.com [RECEIVING.INTERFACE.IP.HERE])
      (using TLSv1 with cipher AES128-SHA (128/128 bits))
      (No client certificate requested)
      by smtp.ourcompany.com (Postfix) with ESMTPSA id 593E0BA56
      for <[EMAIL PROTECTED]>; Sat, 29 Nov 2008 15:20:06 -0500 (EST)

I have attempted to mess around with header_checks assuming that this
is where the REWRITE would go, but it doesn't seem like I'm getting
anywhere.

Is what I'm being asked to do possible?  If so, am I looking in the
right place of header_checks - and would anyone have any suggestions
on how to accomplish this?


Thanks in advance-
