SEndmail +filtering

[Alvaro Rosales R.]

Hi Guys Im running  sendmail in my box , and I would like to filter 
my outgoing mail and send a copy of all the outgoing mail of the server directly to a 
control mail account .Do you have any ideas of how to do this?, I am using 
procmail to filter incoming email, but I don get any hints to filter 
outgoing emails.
Thanks in advance for your answers.
