Multiple exchange servers with single domain

Going trough a merger and need to design new email routing.  Currently have one exchange 2007 server in each domain (connected with full trusts).  Eventually converting to one domain and two separate sites but temporarily we need to start accepting new email addresses   During the trust scenario about the mailboxes will be split pretty evenly across the two domains.  Is there a way for one exchange server to start receiving all email for the new domain and if the mailbox account does not exist on that server forward the email to the exchange server in the other domain.  Thanks!

sounds like you need to create the new domain as an internal relay domain, and configure a send connector pointing to the other server for if they don't exist in your domain.
