how do I control amount of email sent per hour?

[ppc]

I have a plesk 8.1 server(centos) and I would like to know how I can control the amount of mail sent from my server. I will be hosting some sites and I want to make sure there's no abuse.

Can someone tell me how to do this? Also, can I see how much email an individual website is sending?

thanks
