Notes mail routing between domains

I have 2 Domino domainsthe first one has one server and it receives incoming mail via smtp.

all mail that is receives will be sent to the second domain via nrpc and not via smtp.

I have set up a mail routing connection document and an adjacent domain document.

However when mail comes in, the router tries to look the recipient up in the directory, instead of sending it to the second domain.

my question

is this possible

Thanks
