There are a couple of ways to check.
Microsoft has some tests here:
http://support.microsoft.com/default.aspx?scid=kb;en-us;304897 look for
"how to test for relay" about midway down.
What I do is to use the web-based SMTP tool at www.zoneedit.com/smtp.html
and put in my Yahoo external mail addresses for both the FROM and the TO
fields. If the email goes through, then the server is an "open relay".
You'll be able to see the SMTP transaction in the bottom frame when you
click submit. If you see "Unable to relay .. . " you are in good shape.
What should happen is that your server should only relay messages for
yourdomain.com.
To fix an open relay:
Go to the properties for the SMTP virtual server, Access tab, then relay
restrictions. "Only the list below" should be selected, with only the
machines on there that you want.
Hope this helps
