Look at the messages in archives/private/pd-list.mbox/pd-list.mbox. The
archives are threaded by message-id in References: and/or In-Reply-To:

If messages are threaded without one of those headers referencing a
prior message in the thread, then there is a problem with pipermail,
but if the header is there, it is a problem with the user or the
user's MUA.

It's only the display depth that's limited to 4 to keep the page from
growing too wide.
