I've seen a lot of spam with forged headers, making it look like the origin is the ip of the receiver.

I've been told there are a couple of programs that can be installed on the RaQ that filter out spam that has the same originating IP address as the receiver's.

Can anyone point to such a beast?

Thanks,

Jim Whitesell

anyone? please?
