Not send email to user

Hi guys, I need some help or advise. I have my RT to receive emails and send
it to an specific queue and it sends a replay to the author(sender) but I
have a server monitoring application that sends emails when something is
off. I want my rt to NOT send a replay to that email due to the monitoring
application is not programed to receive emails and its keeps looping back.
How can i do that?
