I am configuring a local network and for some reason I can't get server to send an email. I already install the SMTP server and configured using this tutorial http://www.itsolutionskb.com/2008/11/installing-and-configuring-windows-server-2008-smtp-server/ but when I try to send an email using code, the email gets pickedup from mailroot/pickup and dropped in mailroot/queue and stays in queue forever, it never goes anywhere, I even tried dropping a basic mail.txt file with this in it:

to:[email protected]
from:[email protected]
subject:This is a test.
this is a test.

still the same thing happens. Is the smtp server not configured right, is their something else I am missing, because this is my first time setting up an smtp server
