NDRs w/Exchange 2003 using Smarthost

I have a client that is using SBS 2003 w/exchange 2003. He has a smtp connector that is pointing to a Smarthost. He cannot send mail from Outlook 2003 to an email address in his smarthost domain ie xxx@abc.com. He can send mail to anyone outside of his domain.
There are many workers that have email addresses that are not users on the SBS2003. These are the email users that he gets an NDR from.
SBS2003 users get mail OK through the Exchange.
Is the trouble on the SBS2003 or the Smarthost ISP?

Without seeing what the NDR says, it is difficult to say. I would suspect the ISPs domain - perhaps using the wrong smart host. Was the SMTP connector configured using the SBS wizard or manually?

The NDR says The e-mail account does not exist at the organization this message was sent to. Check the e-mail address, or contact the receipt directly to find out the correct address. #<5.1.1>
The email addresses do exist and can be reached from other locations.

As for whether the SmartHost was created with the wizard or manually, I don't know. I was asked to look at this after it was done.
The setting under exchange->connectors> Small Business SMTP the radio button is selected for 'Forward all mail through this connector to the following Smarthost'. mail.domainname.com where domainname has the real domain name. Furthermore :
The setting under exchange->server->protocols->SMTP->Default Virtual SMTP -> properties->Delivery Tab->Advance has the domainname.com in the domain box and mail.domainname.com in the Smarthost box.
