It's possible that he's running a relay server, in which case the default
configuration will not suffice. You can use LDAP lookups against your
internal mail server if that's possible, or output a textfile of valid
local_parts from the internal server and do a lookup against that.
It would be easier to help you if you gave us a few more details about your
setup.
