I have searched the java forums and the most common cause of this error are:

1) antivirus software blocks the connection - make sure that your antivirus software is not blocking on port 25.

2) smtp server unexpectedly terminates the email connection

The user provided feedback:

I was able to get the email connection working. It turns out you were correct. I was testing Automize on my corporate laptop, which has McAfee anti-virus installed. McAfee was set up to prevent email from being sent on port 25 to prevent the spread of email born virus's etc. Once I opened port 25. Email worked fine.
