Hi IFINITEM,
Thanks for posting here.
>1. Mail routing accross the domain A and C pass through the internet and there are regular DNS resolution problems since they share the same router. we will like a situation where mail routing is done without the internet. Mails across the domains
can be resolved internally.
So are these two mail systems where in two sites are using same name space?
Using the Receive Connectors in Exchange system will work.

>2. we will like to also achieve DNS resolution for the hosts in the 3 domains without issue.
Do you mean want to route the mail through internal networking instead over internet ?
