HOWTO: Detect outgoing SMTP mail has left the Queue folder.

This is a C# console app using SMTP to send an email.

The .EML file stays in the Queue folder because I close down the Internet
Connection prematurely.

What's the best way to keep the Internet Connection live until the IIS
server is done sending the email, as evidenced by the .EML file leaving the
Queue folder.

I can send email using C# and SMTP, but keep closing the connection before
the .eml file has left the Queue folder. The length of time the .eml file
stays in the Queue folder is dependent on the size of that file; big or many
attachments increases the time.

If I start an internet connection, issue the smtp mail send and then close
the connection in my C# program, I need to wait until the .eml file has left
the Queue folder. Otherwise, prematurely closing the internet connection
causing IIS to abort the send.

How can I detect that the .eml file has left the Queue folder?
