Neither?

For archive.inbox, simply make your MTA deliver a second copy to there,
or configure the dovecot LDA to put a copy into it. That should be
trivial.

For archive.outbox, you need to make your MTA deliver a copy of the
message to the right folder, with exim that's easy with the unseen
router option (IIRC, but I do know that the exim FAQ contains an entry
answering exactly your question)
