Comment 5 for bug 588411

We will make is simple for team admins to get the mbox or a slice of the mobx. We are solving Lp's mail archive issues with a new project called grackle (https://launchpad.net/grackle) This project will solve many issues that plague pipermail and mhonarc.

Team admins will be able to get the mbox using a URL like
    https://launchpad.net/~switch/+mailinglist-archive/.mbox

Or get get a slice
    https://launchpad.net/~switch/+mailinglist-archive/.mbox?date_range=2012-01-01..2012-01-31

You may not need the mbox if your goal is to get statistics. Grackle will let you request just the headers for a date range to gather counts about messages, threads, and authors.
