This has come up before, but I couldn't find it in the archives with a
quick look, so I wrote a script which you can find at
<http://www.msapiro.net/scripts/post_from_mbox> (mirrored at
This script takes two arguments, the path to a mbox file and a list name
and (re)posts all the messages in the mbox file to the list.
Once the messages reach the list, they will still be subject to all the
membership tests and miscellaneous holds as if they had actually just
been posted to the list.
You could just get a copy of the list's
archives/private/listname.mbox/listname.mbox file and extract the
messages you want (i.e. delete those older and younger that the period
of interest) and use that as input to the script.

There will be side effects. The messages will be re-archived. This means
they will be added to the archives/private/listname.mbox/listname.mbox
file, but they won't appear in the pipermail archive indexes because of
duplicate message-ids, but their HTML files will still be there. Also,
if there are any attachments that were scrubbed and stored aside, they
will be again scrubbed and stored aside. All this results in a little
wasted file space, but beyond that, I don't think anything bad will happen.
