HOWTO: Detect outgoing email has left 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?
