i have added the new registered domain in below

1. organization configuration -> Hub Transport -> Accepted domain

2. create a new mailbox for the new domain

3. from the user mailbox -> property -> E-Mail Addresses -> Add -> enter the new domain mail address

What type of accepted domain did you create? It should be Authoritative. Also did you try sending the email internally and got this message or did you send from an external source and get this message. Based on the steps below if you tested this internally and the new email domain is correct on the mailbox it should work internally with no issues.

Aside from that the only other thing you didn't mention is pointing your new MX record to your external IP of your smart host or your cas/hub server.

Where exactly did you create the MX record? On your internal or external DNS servers?
Did you restart Transport after adding the new domain?

No, receive connectors don't care about the domain. The same receive connector will work for all domains listed in the Accepted Domain list.

Is there something else between Exchange and the internet that has to be updated? If you telnet in to the Exchange server directly and try and send an email to the new domain, does that work?
