[Mailman-Users] question about headers

[Donna]

Hi -

I am just now learning the details of managing a mailman powered 
list. I have previously used majordomo and so far mailman seems to 
have many of the same functions and in fact some much better ones.

Here is my question. At the beginning of all messages to a list there 
are a lot of addresses. For example, on this list all messages have 
this:

>Sender: mailman-users-admin at python.org
>X-BeenThere: mailman-users at python.org
>X-Mailman-Version: 2.0.8 (101270)
>List-Help: <mailto:mailman-users-request at python.org?subject=help>
>List-Post: <mailto:mailman-users at python.org>
>List-Subscribe: <http://mail.python.org/mailman/listinfo/mailman-users>,
>	<mailto:mailman-users-request at python.org?subject=subscribe>
>List-Id: Mailman mailing list management users <mailman-users.python.org>
>List-Unsubscribe: <http://mail.python.org/mailman/listinfo/mailman-users>,
>	<mailto:mailman-users-request at python.org?subject=unsubscribe>
>List-Archive: <http://mail.python.org/pipermail/mailman-users/>

Is there any way to prevent this?

Thank you for your help.
