[exim] To copy salient mail

hello, I have a problem and it does not manage to solve it with the
documentation either nor reading the file of the list.
I need that exim does a copy to me of all the mail salient to a given
account, but single the projections and with the commando to deliver
copies the entrants to me, somebody says to me if this can be done.
Thanks
PS: excuse the translation I am using a translator:D
