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.

That message isn't an Exchange message.
When you are doing the telnet test, what you are you telnetting to?
The smart host?
The Exchange server?

If it is the Exchange server, what else is on the Exchange server? Specifically anything else that could be scanning SMTP traffic?
