Parsing Incoming Email to Separate Business Units

Parsing Incoming Email to Separate Business Units

With an incoming email server setup in the Global Email Configuration, how do I setup two separate Business Units to parse incoming email to create a Request in the appropriate Business Unit? For example, one BU is for Client Service Requests and another BU is for internal Project Requests. But the incoming Global Email Configuration can be setup for only one email server name. (Adding email IDs in the individual Business Unit's email configuration will not work in my case since a contact's email address might be applicable to requests in both Business Units.) Is there a way to parse incoming email to separate Business Units other than by the email ID? (Build 7505)
