[Mailman-Users] HTML-format Attachments in the List Archives

[Barry Finkel]

I have a question about Mailman 2.1.9 archives and HTML attachments.
I have a list where the poster has sent mail that contains

     This is a multi-part message in MIME format.

     --===============7294073253759616889==
     Content-class: urn:content-classes:message
     Content-Type: multipart/related;
	     boundary="----_=_NextPart_001_01C7DE7E.868176F5";
	     type="multipart/alternative"

     This is a multi-part message in MIME format.

     ------_=_NextPart_001_01C7DE7E.868176F5
     Content-Type: multipart/alternative;
	     boundary="----_=_NextPart_002_01C7DE7E.868176F5"


     ------_=_NextPart_002_01C7DE7E.868176F5
     Content-Type: text/plain;

	     charset="iso-8859-1"
     Content-Transfer-Encoding: quoted-printable

     --===============7294073253759616889==--

When I look at the mail in the list archives, my Firefox browser in
Unix shows

     The plain text of the message, converted from q-p format to basic
     ASCII text.
     ------------- next part --------------

When I click on the .gif or .jpeg hyperlinks, I see the images.
But when I click on the .htm hyperlink, I see the HTML text.
If I take that HTML text, save it to /tmp, and then open that file
with Firefox, I see the mail message properly formatted.

I have looked at the ARCHIVE_HTML_SANITIZER variable in Defaults.py,
and I am not clear what value to set so that the .htm hyperlink
will display the formatted HTML source instead of the raw HTML source.
Is this the parameter that I need to change?

I do not do much with HTML-formatted attachments, as I (like others
on this list) believe that they do not belong in e-mail.
