Spoofing email address

Last Modified: 2012-08-14
I have a SBE 2003 R2 server setup for companya.com.  what i want to do is have users send email out using companyb.com but be able to recieve with companya.com.  the issue i have is that we have another server that is not an exchange server hosting companyb.com  when ever i change the primary address in AD to use companyb.com everything works fine until a user goes to email someone who has a companyb.com address.  The server thinks it has to take care of it instead of sending it out to the other server.  Does any one know how to handle this of a short time?  I only need to keep this going for a few weeks.  I guess all i want to do is spoof the email address for out going emails so the reciepents get the right one!  Thanks!!
