IIS 6, windows 2003 SMTP service not sending email

I have recently been trying to install SMTP service on our new server, but been having trouble sending email.

In my case, the solution and instructions are found on this link: http://www.symantec.com/business/support/index?page=content&id=TECH86263

I added the component, tried their IIS SMTP test, but somehow the email was only in the queue.  I already restarted when I installed the SMTP service.

I looked at my IPv4 settings, but I there seems to be something lacking done by our Network Admin.  He forgot to place the DNS for the server.

So I placed the DNS, tried the SMTP send, by placing a text file on the pickup folder, but it still goes to the queue folder under the default folder set-up: c:\Inetpub\mailroot\Queue

As indicated on this microsoft article: http://support.microsoft.com/?id=297700

After sending a few test, and still no positive results.  I decided to restart the server, as the server started, those email in the queue folder was sent and I received all of them.

This was the solution to my problem.  Hope this blog was any help to those who have the same problem.
