How to install SMTP on 2008 server: http://learn.iis.net/page.aspx/751/configure-smtp-e-mail-in-iis-7/

Is this on 2003 server or 2008? I dont see this on 2008 server, under server manager. I dont see SMTP

Thanks Tray, I tried the steps and I ran a VB script I setup to test if the email would get sent and it did not work. If I put my old smtp server in the script it works fine but with this new 2008 server I get error:

Line:     20
Char:      1
Error:     The server rejected one or more recipients addresses. The server response was:550 5.7.1 Unable to relay for "my email address"

Code:   8004020F
Source:  (null)

I found the fix for 2003..I needed to set it up as a smtp relay agent, but now I need to find out how to do it on 2008 server. Anyone have any info on this? Thanks
