Windows7 SMTP and Web.config

I am using Windows7 Ultimate now and have install the IIS on it.  When I was using XP, I had the SMTP Service installed and I coded my web.config files to use the local IIS pickup directory (see code below).   With Windows7, I don't see the SMTP service so I can't use my code:
<mailSettings>
      <smtp deliveryMethod="PickupDirectoryFromIis" from="contact@domain.com.com, My Domain">
           <network defaultCredentials="true" host="(localhost)" port="25"/>
      </smtp>
</mailSettings>


Is there a SMTP service I can install on Windows7?
If not, how should I code my web.config to allow the local system to send mail out?
Or, is there a new way doing it all together?


Thanks.
