[Exim] CC all incomming email to Audit Mailbox

I would like to keep track of all incoming email, therefore I would like all
email that comes into my mail server to go into an audit mailbox, but also
the mail to be placed into the correct user's mailbox as well. Is it
possible to configure exim to do this? if so how do I? I am running exim
version 3.36.

Thank you
