[exim] copy email going to one domain

I would like to keep copies of emails that I send to one particular
domain in a separate folder.

In other words, I want exim to add cc:me to emails that are sent to one
particular domain.

Is this something exim can do, and if so, where would I start?

(nothing nefarious about this; I use my personal email for work, and I
want to cc: myself on all work email as I use a variety of MUAs and it's
hard to keep track of what I sent to whom.)

Thanks!
