I am trying to set up secured routing between two domains with an external domain within the routing path (INTERNALDOMAIN<>DOMAINSMTP<>VENDORSMTP).
Messages are routing out to the VENDORDOMAIN, but when I trace route, the trace fails with the error “No route found to domain DOMAIN from server SERVER/DOMAINSMTP via server SERVER/INTERNALDOMAIN” (address formatted “CNNAME/OUNAME/ONAME@INTERNALDOMAIN”). I have not yet received a message through this route from VENDORDOMAIN.
I have domain documents:
INTERNALDOMAIN -
(adjacent)DOMAINSMTP
(non-Adjacent)VENDORDOMAIN via DOMAINSMTP
DOMAINSMTP -
(adjacent)VENDORDOMAIN
(adjacent)INTERNALDOMAIN
I have connection Documents:
INTERNALDOMAIN -
(LAN-mail)INTERNALDOMAIN to DOMAINSMTP
(SMTP-mail)INTERNALDOMAIN to DOMAINSMTP
DOMAINSMTP -
(LAN-mail)DOMAINSMTP to INTERNALDOMAIN
(SMTP-mail)DOMAINSMTP to INTERNALDOMAIN
(LAN-mail)DOMAINSMTP to VENDORDOMAIN
I have Smart Host on DOMAINSMTP pointing to INTERNALDOMAIN server and ENABLED for all local internet recipients.
I am at a loss at this point to what I am missing or have mis-configured. Any help would be greatly appreciated (ps - looked though posts, but found nothing relevant to this particular configuration)
