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!!

You don't just want to "spoof" the email address you need to configure things properly.

How is your email currently being received by the Exchange Server?  Are you using SMTP?  Or the POP3 Connector?

If SMTP then you need to follow this KB article:  http://support.microsoft.com/kb/321721

If POP3 Connector, then follow this one:  http://support.microsoft.com/kb/300681

For info on how to configure multiple domain names in Exchange properly, see:  http://sbs.seandaniel.com/2004/10/hosting-multiple-domains-on-sbs-2003.html
