Exchange relaying address space vs smart host

[pollardhimself]

Trying to understand the address space and smart host options. Whats the difference?

Is the address space just the email address this send connector will route?

I going to be relaying message from my exchange server to my external email provider.


FROM EMAIL SERVICE PROVIDER

[FONT=&quot]the IP address of the server/firewall, I can relay out for your Exchange Server. I can add an SPF record for your server to the DNS.[/FONT]

So would I just add smart host for my external email provider?

Would this be a correct configuration
