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.

added if a message was held for moderator approval and later accepted.

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