SMTP Mail Routing Problem

This is my first R6 server and I’m experimenting on SMTP Mail Routing and got stuck. I have 2 domains, TestDomain & MailDomain. I can send and receive mail from within my TestDomain but I cannot receive from outside. When I try to send mail from MailDomain,I’m getting an error.

What am I missing or what can I do to receive incoming mail? How can I allow MailDomain to relay message to TestDomain without compromising the live mail server if it’s possible.

Thanks.

Are you referring to Notes mail routing when you speak of domain or do you mean domain in the sense of internet domain?

Which domain will have doing outbound SMTP mail?

I’m referring to the notes mail. The MailDomain will be doing the outbound SMTP mail. What I’m trying to do is create a test network where some users can try R6 mail features before we migrate to R6.
