"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.

I don't see a problem there.
The email was queued for delivery, you simply didn't end the session, so it timed out.

It is timedout.
Simon Butler (Sembee)ConsultantCommented:
Once the message has been accepted for delivery, you need to end the session. That is usually done with something like quit or exit. Otherwise the session remains open because you might be sending another message. Eventually it will time out.
