When users send emails to some china addresses some of the emails are not getting through and some are.  These messages just started out of nowhere and i am not sure how to trouble shoot.  

I have done some looking around but i am unable to locate any help on this issue.  Here is an example of the error msg users get when sending mail to these addresses.

     user@xyz.cn on 10/23/2006 4:09 PM
            The e-mail system was unable to deliver the message, but did not report a specific reason.  Check the address and try again.  If it still fails, contact your system administrator.
            <exchange.domainA.com #5.0.0 smtp;551 User not local; please try <forward-path>>

We are running Exchange 2003 with a mail relay server running mail essentials and mail security.

any idea would be great!

thanks,

The message is being generated by the remote server.

If it doesn't happen for all messages then it is probably a misconfigured server at the remote end doesn't recognise that the domain is one it is responsible for, or someone has made an error in the MX records for the remote domain and has a server listed that they shouldn't.

Either way, there is very little you can do about it.

You could try sending the email via your ISPs SMTP server using an SMTP Connector, but as the problem is with a remote server that will probably still generate the messages.

The recipient needs to fix the problem - nothing you can do.
