We're running Server 2003/2008R2 domain with Exchange 2003 standard. We have a "dual" domain going, with soastc.local used internally on private address space and soastc.org external. My Exchange server is configured to receive soastc.org mail and pass it on to users in the .local domain. So far so good, everything is working.
After 34 years, they decide to change the name of the organization. I registered a domain for the new name, and of course, they want to be able to receive e-mail at the new domain name as well as the old one (at least for now). I dug out "Mastering Exchange Server 2003" and started reading up. I ran across the claim in the book that I can just assign proxy addresses, even with different domains to users, as long as I point the MX record for the new domain at my server. I did that, and gave myself a kairosnw.org address, but when I try to send to it from outside, I get this: ----- The following addresses had permanent fatal errors ----- <[email protected] <javascript:top.opencompose('[email protected]','','','0')> > (reason: 550 Requested action not taken: mailbox unavailable) ----- Transcript of session follows ----- ... while talking to smtp.kairosnw.org.: >>> RCPT To:<[email protected] <javascript:top.opencompose('[email protected]','','','0')> > <<< 550 Requested action not taken: mailbox unavailable 550 5.1.1 <[email protected] <javascript:top.opencompose('[email protected]','','','0')> >... User unknown Reporting-MTA: dns; webmail.userservices.net Received-From-MTA: DNS; localhost.localdomain Arrival-Date: Thu, 22 Mar 2012 16:16:50 -0700 Final-Recipient: RFC822; [email protected] <javascript:top.opencompose('[email protected]','','','0')> Action: failed Status: 5.1.1 Remote-MTA: DNS; smtp.kairosnw.org Diagnostic-Code: SMTP; 550 Requested action not taken: mailbox unavailable Last-Attempt-Date: Thu, 22 Mar 2012 16:16:50 -0700 So, is the book wrong? Am I missing some part of the picture? It would appear that if I want to assign a second IP address to my Exchange Server, I can create a second SMTP Virtual Server for the second domain, but I'm not sure that I want to do that (especially if I don't have to).
