I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This usually indicates that you are attempting to send more emails at once than the server receive connector is configured to handle.


As it's a test email it's unlikely you're sending more than one email at a time - may be worth checking to ensure there's no virus trying to spam out on the machine. Would also be worth checking the configuration on the server for the account in question. If you setup a different account on the same machine does it have the same error?
