title: Regarding mailserver installation on IIS 7
body: <p>i tried to send emails from my ASP.net 4 application, it did not work!!
  it worked only on hosting server. so i need to install a mail server on my server. the problem is that i have a small intranet with access to internet through a dynamic ip.
  does installing of mail server on windows server 2008 requires static IP directly connected to the internet?</p>
