Summary: Multipart/mixed issues in archives
Initial Comment:
We are having problems with mailing lists that are not
being properly stripped down to text content in the
archives. When there is multipart/mixed, it doesn't
pull the multipart/alternative sections into their
appropriate text portions.

  For example, from content such as the following:

==============================================================================
...
From ...
[...]
Content-class: urn:content-classes:message
MIME-Version: 1.0
Content-Type: multipart/mixed;
boundary=------------InterScan_NT_MIME_Boundary
[...]
This is a multi-part message in MIME format.

--------------InterScan_NT_MIME_Boundary
Content-Type: multipart/alternative;
        boundary="----_=_NextPart_001_01C336A1.2C7564BC"
Content-Transfer-Encoding: 7bit


------_=_NextPart_001_01C336A1.2C7564BC
Content-Type: text/plain;
 charset=us-ascii
Content-Transfer-Encoding: quoted-printable

Kevin has a pending checkin that addresses the
minss/maxss issue.

As you can see, the actual content of the
multipart/alternative portion [text/plain and
text/html] were completely stripped out  instead of
being shown a plain text.

The patch by q7joey is merged into my Scrubber.py patch
#866238. I hope Barry can integrate it in 2.1.4.

i have a few line patch that seems to make it do what is
expected.

i can't see how to attach via sourceforge yet, so i'll paste
it here:

This fails for many of my users as they habitually attach a 
photo of themselves in their signatures. They are incredulous 
at the idea that mailman can't handle it.

Thanks

i agree that this should be a high priority issue.  a simple
message with just multipart/alternative will show up in the
archive ok, but if there is any other kind of attachment,
then the entire multipart section is skipped and you just
get a link for the extra attachment for download/view
ability.  i haven't started to look at the code (and i'm not
a python/mailman person), but i'll report anything i can find.

Additionally I think it is appropriate to up the priority on this 
bug as it causes key functionality to fail.

This is causing me real problems! Is there any known 
workarounds?

If I can't fix this I might have to use a different package as 
presently all my archives are useless!

This appears to be within:

def process(mlist, msg, msgdata=None):

at around line 276, but I saw no way of making it recurse
for multipart/[mixed|alternative] sub-MIME parts.
