Hey Stephen. Thanks for your help. I passed on your comments to DH and
this is what they said:

        The web interface has the same problem as the mail interface --
        the logs rotate and are not available after a certain span of
        time. Everything else in [Stephen's] email is theoretical and
        not applicable to our installation as it exists now.

It just seems goofy, given that they allow us to use Mailman for a
discussion list, but not as an announcement list. The only practical
difference between the former and latter is that only one person is
typically allowed to post in the latter case, whereas both situations
can potentially have a post with thousands of recipients.
