Assuming you have already installed the SMTP feature.  In IIS 6 Manager (because SMTP services are still unchanged since IIS6):

1. right click on the SMTP server and select "Properties"
2. click on the "Delivery" tab
3. click on the "Advanced" button
4. in the "Smart host" field, enter the IP address (172.16.10.110) or name of the destination host
4a. I would also fill in the "Masquerade domain" field with your public domain name (YourDomainName.com)
5. OK all the way out...

You may have to authorize the DMZ server to be allowed to relay to your internal servers.  So you may have to modify the server at 172.16.10.110 to say allow this server (192.168.1.100) to relay thru me.

You may have to open firewall rules on the server in the DMZ, thru Windows Firewall.

If there is an actual firewall appliance (server) controlling network flow, you might have to open a rule there that defines 25/tcp open inbound from 192.168.1.10 to 172.16.10.110.

Also, is there a process that is building and sending emails locally?  Then you may want to define the local access in the DMZ SMTP service.  Meaning, from where (localhost) something can relay using the DMZ server.

In IIS6 Manager:

1. right click on the SMTP server and select "Properties"
2. click on the "Access" tab
3. click on the "Relay" button
4. leave the "Only the list below" option selected
5. click "Add" and enter the IP address 127.0.0.1 and 192.168.1.100.
6. OK all the way out...

This tells the SMTP Service that a process running locally can relay.  And a process that (for some reason) attaches to the 192.168.1.100 address can also relay.
