[exim] Filter

I have a my mail server setup so that all incoming messages get relayed
to a spam scanning server. Once a day the server sends a message to the
users letting them know what messages have been quarantined. The problem
I am having is that when the spam server sends the message it gets
routed back to spam server. Is there a way in the exim.conf that I can
specify that if a messaged is sent by this server to just deliver it
without sending it back? I am unsure what the syntax of this would look
like.

Any help would be appreciated.
Thank you,

Andrew
