Have Exim lookup each recipient in the Domino directory through LDAP.
Add this to your router.
local_parts=\
ldap; ldap:://dominoserver/?mail?\
sub?(&\
(|\
(objectClass=inetOrgPerson)\
(objectClass=dominoServerMailInDatabase)\
)\
(|\
(uid=$local_part)(cn=$local_part)(cn=$local_part@???)(mail=$local_part@???)\
)\
)
This should take care of aliases as well as mailin databases.
Make sure you replace yourdomain.com with your actual mail domain.
