Doh! I really should drink my coffee before answering these.
I've written some stuff that does this for Pipermail. It's not as easy
as you think. The hardest part is editing the mbox file that is used
for archive storing and for rebuilding the archives. You've got to pull
the old mail out of the mbox, while keeping the current mail.
If you can get that part done, then the rest follows nicely.
You can use a trigger email that is sent to the archives monthly (mine's
cleverly disguised as a monthly mailing list policy reminder). If you
use that as your anchor within the mbox file, then cutting the file is
Good Luck - Jon Carnes
