If you're using something like the default ACLs, I suggest moving

  accept  hosts         = +relay_from_hosts


accept authenticated = *

earlier, so that they appear after the require verify = sender clause.
Then you can add something like the following after your dnslist checks:

deny recipients = lsearch;/etc/exim/internal_only_addresses
