We have decided to host our own mail using our existing exchange server. I made the changes to our domain record at network solutions to point back to our external IP address.
I contacted our hosting company that hosts our domain and made the changes to the A record and MX record. on the MX record It reads:
tdcb.com. MX IN 1800 exchserver.tdcb.com
our exchange server is named "exchserver" but our local domain is tdcb.local so it's exchserver.tdcb.local. do i need to change the MX record to look like:
tdcb.com. MX IN 1800 exchserver.tdcb.local
The problem is when I send mail to a account on our exchange server it gets bounced back with:

Any ideas what the problem is?
