Mail routing between 2 domain

Hi,I have 2 domino server of different domain.

Domain ABC and Domain XYZ.

Domain XYZ would like to send mail to Domain ABC users in such a way → type ahead will display user as user1/aaa/ABC, click send will resolve to user1@abc.com.

I have created a edc.nsf and add in to Domain XYZ directory assistance.

Type-ahead is able to display user1/aaa/ABC, but when click send, mail router will return failure and say no route to path ABC.

Anyone knows???

Regards

Lee
