This may not be exactly what you are asking for but it looks like your
struggling with your current approach . The way I see it you have a
couple of options which all achieve the same thing with various levels
of difficulty and elegance.
1) Query against an LDAP directory or "local users" and manualroute
accordingly
2) Use a manual list/cdb of names and use a redirect router
3) Deliver everything to exim and forward all unknown to exchange
4) Deliver everything to exchange and forward all unknown to exim
The following articles and threads may help, or just google "exchange
forward unknown users". (A mis-match in the exchange "alias" entry has
caused me lots of problems in the past).
