Initial Comment:
Platform: TRU64 v5.1a

I'm using Mailman v2.1b5 and have noticed the following problem when archiving attached files.

MS-Excel documents are not getting properly archived. Well, the file that is posted appears unharmed in the ...archive/<list>/attachments/... directory on the server, but it isn't available as an attachment from the posted message. A few lines are garbage are there instead.

MS Word, Powerpoint, PDF files are OK from what I've tested although I've found a similar problem to above with a Word document when using 'arch' on an existing mailbox.

Ie, arch creates the html pages OK and extracts the attachments OK, but a Word document isn't available from the message.

I think the problem you're seeing is that with Excel
spreadsheets, your browser is displaying the binary data to
you instead of offering to save it to disk, as it does for
Powerpoint files.

Here's the problem: we don't trust the file extension on
attachments, but instead, we look the Content-Type up in
Python's mimetypes module to find the file extension that we
use when saving the attachment to a file. 
application/vnd.ms-excel are reversed mapped to .xlb
extension but your browser probably doesn't know what to do
with .xlb

I think there's little Mailman can do here.  I suggest
right-clicking on the link to save it to a file.
