Adding User as CC based on requestor email


I was wondering what the best way of implementing the functionality of
adding certain users as CC or even AdminCC only on emails requested from
a certain email/domain.

I’ve tried to create a scrip with no luck. Maybe someone can point me in
the right direction?

Thanks in advance.
