Redirect SMTP to an SMTP relay server

hi,

we are an ISP, and we are suffering from many Spams are being sent out our network. Now, I want to redirect the all the outgoing SMTP traffic to the SMTP relay server where I can scan them with the Anti-spam software.

I know that I can redirect the traffic using the PBR, but can any body tell me what's the required configuration in that case?

I have a Cisco 7606 router, and the SMTP relay server is 4 hops away.


regards,
Ameer

What other ISP's have done. Is just blocked all outgoing smtp and told all of their customers to use their relay.
