Presumably, your header list was included in a non-text/plain part that
was removed by this list's content filtering. However, here's an
annotated list of headers typically added or modified by Mailman.

X-Mailman-Approved-At: Sun, 16 May 2010 16:46:02 +0200
  added if a message was held for moderator approval and later accepted.

X-Content-Filtered-By: Mailman/MimeDel 2.1.12
  added if the list's content filtering removed anything

Subject: [Mailman-Users] Cleaning up email headers
  possibly modified by adding the subject_prefix

X-BeenThere: mailman-users at python.org
  added and required to prevent mail loops from misconfigured lists.

X-Mailman-Version: 2.1.12
  added

Precedence: list
  added

List-Id: Mailman mailing list management users
<mailman-users.python.org>
List-Unsubscribe:
<http://mail.python.org/mailman/options/mailman-users>,
	<mailto:mailman-users-request at python.org?subject=unsubscribe>
List-Archive: <http://mail.python.org/pipermail/mailman-users>
List-Post: <mailto:mailman-users at python.org>

List-Subscribe: <http://mail.python.org/mailman/listinfo/mailman-users>,

  The List-* headers are specifid by RFC 2369. They can be suppressed
  by setting include_rfc2369_headers to No on the list's General
  Options admin page.

Sender: mailman-users-bounces+mark=msapiro.net at python.org
Errors-To: mailman-users-bounces+mark=msapiro.net at python.org

  The above two are added/changed by Mailman for bounce processing
  purposes. Unfortunately, the Sender header can cause some Microsoft
  MUAs to display From: 'sender' on behalf of 'from'. See the FAQ at
  <http://wiki.list.org/x/RoA9>.

Note that most MUAs do not display most of these headers by default. As
noted above, you can easily turn off the List-* headers.
