Email 101 Unit Tests (See related posts)

// Two unit tests for my Email 101 code. The first expects connection information to
// be in the System properties. That can be setup as part of running the unit tests
// from either Ant or Eclipse. Note: The first test only confirms that the send occurs
// without error, not that the email was actually received or received at the correct
// address.
//
// The second test trashes the SMTP server name and then confirms that it results in
// an exception being thrown from the mail sending code.
