System.Net.Mail

What are the preferences DASP has for us when we create a ASP.NET v2 framework control using the new System.Net.Mail?

For example, if we declare the network host inthe Web.Config:

<system.net>
<mailSettings>
<smtp>
<network host="?" port="?" userName="?" password="?" />
</smtp>
</mailSettings>
</system.net>

Localhost, no port, no username, no password?
Thanks guys
