Content filters are set up on an individual email account, on a domain.

I recently found a different option than filters that might work out better.
Under Settings > Domain Settings > Events
We have an event set up that any email that comes in for a certain domain sends an auto responder to the original sender and then sends a copy of the original email to me (different domain)
