Hiya, I setup a SBS2011 installation at home and changed the DNS at my ISP for the FQDN to point at my home static IP. I set it up at it all works mostly fine at least email did. I have now moved it to the office site where it will live and work, I setup the ISP as the mail.relay and changed the DNS wll good, and setup an mx record, but now all emails bounce back apart from the ones to the FQDN quoting amongst other things x-originating-ip xxx.xxx.xxx.xxx which is my static IP at home? I think if I change this record in Exchange all will be well again, Thx Christian

Hi Have you changed the MX to point to the new location/ip? Is the firewall allowing the incoming traffic and sending it to the server? What does the NDR say? Do you have the appropriate PTR records in place?
