How to remove Received from field?

Hi
 
Without explaining here (see below) I would like to remove the
"X-Message-Info" and the "Received: " fields from mail sent to a list.
 
I have managed to remove the X-Sender and X-Originating-Email by editing the
rc.submit/rc.local.s20 but using the same technique foe the other fields
does not work.
 
I have the following in the rc.local.s20 file:
 
    :0 fhw
     | formail -IX-Message-Info: -IReceived -IX-Sender:
-IX-Originating-Email:

Can someone advise how I might do this?
 
========================
Now if you want to know why I want to do this its not some sinister hack,
actually quite simple. 
 
I maintain several email lists totalling about 70,000 names and it is a
hazard that some people get on the list by accident. I always provide for
unsubscribing and as a very public figure (I am a member of the Parliament
in my country) I am aware of the SPAM implications.  
 
However because I travel so much I redirect all my email from various
accounts to a Hotmail Premium account which allows me to use Outlook to
manage the address database and also to send and receive hundreds of emails
daily from anywhere and on any internet connection. 
 
Also I can use Frontpage to construct "nice" email newsletters which then
uses Outlook to send them to the list via my Hotmail account. So far so
good!
 
However it only takes 3 (I repeat just 3 people!) to complain to Hotmail
about SPAM and they will shutdown your account AUTOMATICALLY without any
contact or question even though you are a paying premium customer!
 
So I am happy for people to contact me to either abuse me and/or to ask for
removal from the list however I want to hide the fact that the original
email was sent via my Hotmail account and the headers of the newsletter
still have the header information like this:
 
X-Message-Info: txF49lGdW41bSEufHX0Z8j6mSUSlMGNAGUJvcjBa8gk=
Received: from host.our-web-host.com ([209.239.36.67]) by
bay0-mc12-f19.bay0.hotmail.com with Microsoft SMTPSVC(6.0.3790.1830);

As you can see from the above rc.local.s20 file these headers stay in!
 
thanks
