Applying Exim custom filter only per specific attributes

Hello, I wish to apply an Exim custom filter but that it will be realized only if specific attributes exist: Either Exim client that is coming from "NOT source IP ranges" (meaning it will apply only for client IPs that are NOT from a list of IP ranges I will supply) or by any delivery that is intended to be relayed to domains that are not managed by the local Exim. I will glad to get and idea or direction how to do this. Thanks.
