How about checking for mail of non-local origin rather than checking
the destination:

(All examples are untested)

fetchmail allows you to set the port number it will submit mail to in
the "smtphost" option (eg: "set smtphost localhost/2525" in fetchmailrc ),
set up exim to listen on the new port (eg: 2525) port and check the
port number in your ACL. to do this use a condition test instead of the
domains test.

eg check for emails received on port 2525:

condition = ${if = {$received_port}{2525}}

This is open to "abuse": should anyone on your LAN explicitly wish
their emails to be scanned they could configure their client to
submit to your port 2525.
