Assuming you have already installed the SMTP feature. &nbsp;In IIS 6 Manager (because SMTP services are still unchanged since IIS6):<br />
<br />
1. right click on the SMTP server and select &quot;Properties&quot;<br />
2. click on the &quot;Delivery&quot; tab<br />
3. click on the &quot;Advanced&quot; button<br />
4. in the &quot;Smart host&quot; field, enter the IP address (172.16.10.110) or name of the destination host<br />
4a. I would also fill in the &quot;Masquerade domain&quot; field with your public domain name (YourDomainName.com)<br />
5. OK all the way out...<br />
