Filter outbound SMTP from ISP

[Paulo Roncon]

Helo all,

I'm wondering if there's a way to filter ALL Outbound SMTP in a ISP before it goes to their destination MTA?

I have a working mailscanner server that filters from:ALL to my domain. This is simple to achieve.
What i'm aiming at is: Filter all SMTP traffic from my ISP networks between its origins and its destination.

Is there a way to say to my MTA to accept all SMTP traffic that goes to him, filter the mails, and send them on their way?

Can this be done?
Ideias?

Thanks,
