How to handle multiple emails to the same domain

Hello,

I am very newbie to procmail. I would appreciate being pointed to a
resource to help with the following question:

        If a single email message is sent to two or more users
        in the same domain, my .procmailrc sends the message to
        only the first matching username. Therefore, a single
        email sent to me(_at_)mydomain(_dot_)com with a cc: to 
you(_at_)mydomain(_dot_)com
        will be sent to the first match (me) and no copy will be sent
        to you.

I assume that the solution might involve a more sophisticated search for
other addresses in the TO, CC and BCC fields. But maybe I'm wrong and there
is a more elegant way to handle this?

Thanks,

 - Jim
