We are going to bring a new group of users into our corporate email service. They must retain their @filecreator.com email addresses.  They are currently running on their own mail service since before the acquisition.
While trying to decide the best strategy to define this in LDAP, so that users who have been switched over to the corporate email service will get delivered "locally" and users who are still on the old systems will be routed to the old systems, we noticed it is already defined in our LDAP as this entry:


dn: dc=filecreator, dc=com, o=internet
objectClass: top
objectClass: domain
objectClass: inetDomain
objectClass: mailDomain
dc: filecreator
description: DC node for filecreator.com
inetDomainStatus: active
mailDomainStatus: active
mailRoutingHosts: ns2.filecreator.com <<<<<<<<<<<<<<<<<<
inetDomainBaseDN: dc=filecreator,dc=com,o=internet

Note that there is NOTHING defined under dc=filecreator,dc=com,o=internet, so it can never find any users/groups there.

We do NOT have route_to_routing_host set. The default is 0.

From msconfig:
instance.base.hostname = mshost.abc.com

Question: It is working in that the presence of the dc=filecreator,dc=com,o=internet object is not causing any problem with routing to that domain.  Why is this working?  From the imsimta test -rewrite output, why was it NOT trying to lookup users in that domain and then failing?  Is the lack of any users/groups objects under the container indicated by inetDomainBaseDN enough to cause it to not treat the above LDAP entry as a valid domain?
