I know this is a frequent problem, but I can't find the accurate answer here. 
 
I had to rebuild Windows Small Business Server 2003 due to a VERY nasty malware that crippled the servre. 
 
We rely on a smart host (because we have a dynamic IP address) to deliver the mail. 
 
After looking through here, I followed instructions to test the server: 
 
telnet xxx.xxx.xxx.xxx 25 
HELO test 
... 
RCPT TO: test@test.com 
 
then it comes with this error: 
553 sorry, that domain isn't in my list of allowed rcpthosts 
 
I have added our domain to the receiptent policy. 
 
I'm at a loss. 
 
Maybe someone can help me walk through this issue.
