In Forefront Online Protection for Exchange (FOPE), the Intelligent Routing feature is a function of Group Filtering feature. Intelligent Routing redirects a subset of users’ messages to specific delivery locations based on Virtual Domain IP Address Settings, even if users all share the same domain. For example, an office based in the U.K. can receive all mail for U.K. users at a specific location, one that is different than the destination for mail sent to U.S. users. As with Group Filtering, each user is associated with a Virtual Domain. Each Virtual Domain is then configured to redirect email to specific servers within the organization.
You will need to configure the receiving mail server within your environment to accept email for the Virtual Domain namespace. In order to change the recipient address back to the original Parent Domain naming, the recipient address needs to be re-written by the receiving mail server. If the recipient address is not rewritten by the receiving mail server, then the user would be able to view the Virtual Domain name in the message header. When the end user replies to a message which was routed using this functionality, the Reply-To address for the end user would not be affected, as this is stamped by the sending server (your mail server) based on the Primary SMTP proxy address associated with the user in your environment.
