The tree is like this (according to claws-mail)
1) * message/rfc822 (3.29MB)
2) ** multipart/alternative (3.29MB)
3) *** text/plain (1.14KB)
4) *** multipart/related (3.28MB)
5) **** text/html (3.83KB)
6) **** image/jpeg (3.28MB)

1) Mime-Version: 1.0 (Apple Message framework v753.1)
Content-Type: multipart/alternative; boundary=Apple-Mail-63-807922156

The filter options:
* filter_content: yes
* filter_mime_types: <none>
* pass_mime_types:
> multipart/mixed
> multipart/alternative
> text/plain
* filter_filename_extensions:
> exe
> bat
> cmd
> com
> pif
> scr
> vbs
> cpl
* pass_filename_extensions: <none>
* collapse_alternatives: yes
* convert_html_to_plaintext: yes
* filter_action: discard

The resulted mail contained only (3) and had these headers:
X-Mailman-Approved-At: Tue, 25 Jun 2013 04:35:52 +0200
X-ContentX-Mailman-Approved-At: Tue, 25 Jun 2013 04:35:52 +0200
X-Content-Filtered-By: Mailman/MimeDel 2.1.13-Filtered-By:
Mailman/MimeDel 2.1.13
Content-Type: text/plain; charset="utf-8"; Format="flowed"; DelSp="yes"

So multipart/related is not in the allowed MIME type and was filtered.
I think it is no bad idea to have the above filenames filtered, while
everything else should pass landing in the archive. Please give me a
hint, how to archieve this.
