Relay not permitted

I'm getting the following message when I try emailing one particular domain:

550 relay not permitted

I'm using Symantec Mail Security for MS Exchange 6.5 and Windows Small Business Server 2003.

Is this coming from SMSME or Exchange?

Thank you!

Yes, through Outlook.

We are sending to an outside domain.  We have no problems with any domains, except on particular one.
