+++ This bug was initially created as a clone of Bug #745012 +++

Description of problem:

If you ask Mailman to not archive a list but fail to ask it to keep the (disabled) archives private the attachments sent to that list will be placed in a public archive.

This problem is made worse by the default httpd config included in the rpm which turns on directory listings for the public archives:

    ...
    <Directory /var/lib/mailman/archives/public>
        Options Indexes MultiViews FollowSymLinks
    ...


Mailman maintains an index of all messages that belong in the archive including links to their attachments so it would make a lot more sense to disable Options Indexes for /var/lib/mailman/archives/public.


Version-Release number of selected component (if applicable):

mailman-2.1.9-6.el5_6.1



How reproducible:

Always.


Steps to Reproduce:

* Create a test list with settings:
archive = 0
archive_private = 0

* Send a message to the list with an attachment.

* Go to: http://SITE.ADDRESS/pipermail/TEST-LIST/attachments/ [^]

* Follow the directory listings to your attachment.

 
Actual results:

Attachment for unarchived list can be found by guessing a constant directory component and then following the directory indexes.


Expected results:

Nothing is archived for unarchived list.

Description: Mailman is software to help manage email discussion lists, much
           : like Majordomo and Smartmail. Unlike most similar products, Mailman
           : gives each mailing list a webpage, and allows users to subscribe,
           : unsubscribe, etc. over the Web. Even the list manager can
           : administer his or her list entirely from the Web. Mailman also
           : integrates most things people want to do with mailing lists,
           : including archiving, mail <-> news gateways, and so on.

So is it only about disabling indexes in httpd conf, or mailman stores private attachments in public directory for you?

I've intended for this bug to be about disabling indexes in httpd.conf as it exposes this problem and is not suggested in the Mailman installation documentation.

The root cause of the problem is of course that Mailman stores these attachments in the archive when archiving is disabled so no list admin will think about marking the archive private, but it seems a bigger issue and just disabling the indexes will be a big help.

There is already a bug in the vicinity of the root cause in Mailmans bug tracker:
