Sitting in the queue does not mean that it's been sent anywhere. Is there just one message or more than one?

What errors do you see in the log files that relate to these messages?

Two messages, and can't sent to recepients because network connections time out.

What errors do you see in the log files that relate to these messages?

I don't get any error here..

Please advise.....

You must have some information in the logs about that message, what do you see and what about the other part of my question?
