     The purpose of this article is demonstrate how to send an authenticated email.

This article has accompanying files

Up to a few months ago, all of my emailing applications were working great! Then one day the IT department of our parent company "turned off" the SMTP Relay for our Email Server. Dreadfully, this caused all of my emailing applications to blow up. Fortunately, this was only a temporary set back.

My company has been slowly moving away from our parent company. So recently, they decided to outsouce our Emailing client. Which actually turned out pretty nice. I was happy to find that I'd be able to fix all of my emailing programs!

However, because our new emailing client required Authentication, my simple emailing lines of code were not enough to avoid the error:

"The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Authentication required"

Adding Authentication to my emailing code solved my problems! Because of this, I thought there might be someone else in the world that could use this information.

So I have put together a little emailing demo for you. I really hope it helps you!

For your own safety, please:
  1. Re-scan downloaded files using your personal virus checker before using it.
  2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.

If you don't have a virus scanner, you can get one at many places on the net
