[Exim] Stripping Received Headers

Hi,

does anybody know, how to modify the header of outgoing
messages, that nobody can see the received hops from the
intranet ?

I.e. a message sent out has this header

>From testuser@??? Tue Jul 16 12:48:05 2002

Return-path: <TestUser@???>
Received: from mail.tiri.li ([195.226.126.136] helo=mail.tiri.li)
        by tiri.li with esmtp (TLSv1:DES-CBC3-SHA:168)
        (Exim 3.35 #1)
        id 17UPsD-0005WH-00
        for tom@???; Tue, 16 Jul 2002 12:48:05 +0200
Received: from mailinfo by mail.tiri.li with scanned-ok (Exim 3.35 #1)
        id 17UPpt-0000eU-00
        for tom@???; Tue, 16 Jul 2002 12:45:41 +0200
Received: from de188w20.intra.tiri.li ([192.168.10.25])
        by mail.tiri.li with esmtp (Exim 3.35 #1)
        id 17UPpt-0000eM-00
        for tom@???; Tue, 16 Jul 2002 12:45:41 +0200
Subject: TEST
To: TESTER@???

And I want it to strip to

>From testuser@??? Tue Jul 16 12:48:05 2002

Return-path: <TestUser@???>
Received: from mail.tiri.li ([195.226.126.136] helo=mail.tiri.li)
        by tiri.li with esmtp (TLSv1:DES-CBC3-SHA:168)
        (Exim 3.35 #1)
        id 17UPsD-0005WH-00
        for tom@???; Tue, 16 Jul 2002 12:48:05 +0200
Subject: TEST
To: TESTER@???

So that nobody could imagine my internal infrastructure.

Thank you for your help.

Thomas
